The Dutch have made contributions to art, science, technology and engineering, economics and finance, cartography and geography, exploration and navigation, law and jurisprudence, thought and philosophy, medicine and agriculture. The following list is composed of objects, ideas, phenomena, processes, methods, techniques and styles that were discovered or invented by people from the Netherlands.

The De Stijl school proposed simplicity and abstraction, both in architecture and painting, by using only straight horizontal and vertical lines and rectangular forms. Furthermore, their formal vocabulary was limited to the primary colours, red, yellow, and blue and the three primary values, black, white and grey. De Stijl's principal members were painters Theo van Doesburg (1883–1931), Piet Mondrian (1872–1944), Vilmos Huszár (1884–1960), and Bart van der Leck (1876–1958) and architects Gerrit Rietveld (1888–1964), Robert van 't Hoff (1888–1979) and J.J.P. Oud (1890–1963).

Brabantine Gothic, occasionally called Brabantian Gothic, is a significant variant of Gothic architecture that is typical for the Low Countries. It surfaced in the first half of the 14th century at Saint Rumbold's Cathedral in the City of Mechelen. The Brabantine Gothic style originated with the advent of the Duchy of Brabant and spread across the Burgundian Netherlands.

The Dutch gable was a notable feature of the Dutch-Flemish Renaissance architecture that spread to northern Europe from the Low Countries, arriving in Britain during the latter part of the 16th century. Notable castles/buildings including Frederiksborg Castle, Rosenborg Castle, Kronborg Castle, Børsen, Riga's House of the Blackheads and Gdańsk's Green Gate were built in Dutch-Flemish Renaissance style with sweeping gables, sandstone decorations and copper-covered roofs. Later Dutch gables with flowing curves became absorbed into Baroque architecture. Examples of Dutch-gabled buildings can be found in historic cities across Europe such as Potsdam (Dutch Quarter), Friedrichstadt, Gdańsk and Gothenburg. The style spread beyond Europe, for example Barbados is well known for Dutch gables on its historic buildings. Dutch settlers in South Africa brought with them building styles from the Netherlands: Dutch gables, then adjusted to the Western Cape region where the style became known as Cape Dutch architecture. In the Americas and Northern Europe, the West End Collegiate Church (New York City, 1892), the Chicago Varnish Company Building (Chicago, 1895), Pont Street Dutch-style buildings (London, 1800s), Helsingør Station (Helsingør, 1891), and Gdańsk University of Technology's Main Building (Gdańsk, 1904) are typical examples of the Dutch Renaissance Revival architecture in the late 19th century.

Cape Dutch architecture is an architectural style found in the Western Cape of South Africa. The style was prominent in the early days (17th century) of the Cape Colony, and the name derives from the fact that the initial settlers of the Cape were primarily Dutch. The style has roots in medieval Netherlands, Germany, France and Indonesia. Houses in this style have a distinctive and recognisable design, with a prominent feature being the grand, ornately rounded gables, reminiscent of features in townhouses of Amsterdam built in the Dutch style.

The Amsterdam School (Dutch: Amsterdamse School) flourished from 1910 through about 1930 in the Netherlands. The Amsterdam School movement is part of international Expressionist architecture, sometimes linked to German Brick Expressionism.

The Rietveld Schröder House or Schröder House (Rietveld Schröderhuis in Dutch) in Utrecht was built in 1924 by Dutch architect Gerrit Rietveld. It became a listed monument in 1976 and a UNESCO World Heritage Site in 2000. The Rietveld Schröder House constitutes both inside and outside a radical break with tradition, offering little distinction between interior and exterior space. The rectilinear lines and planes flow from outside to inside, with the same colour palette and surfaces. Inside is a dynamic, changeable open zone rather than a static accumulation of rooms. The house is one of the best known examples of De Stijl architecture and arguably the only true De Stijl building.^[1][2]

The Van Nelle factory was built between 1925 and 1931. Its most striking feature is its huge glass façades. The factory was designed on the premise that a modern, transparent and healthy working environment in green surroundings would be good both for production and for workers' welfare. The Van Nelle Factory is a Dutch national monument (Rijksmonument) and since 2014 has the status of UNESCO World Heritage Site. The Justification of Outstanding Universal Value was presented in 2013 to the UNESCO World Heritage Committee.

An architectural movement started by a generation of new architects during the 1990, among this generation of architects were OMA, MVRDV, UNStudio, Mecanoo, Meyer en Van Schooten and many more. They started with buildings, which became internationally known for their new and refreshing style.^[vague]

The Dutch door (also known as stable door or half door) is a type of door divided horizontally in such a fashion that the bottom half may remain shut while the top half opens. The initial purpose of this door was to keep animals out of farmhouses, while keeping children inside, yet allowing light and air to filter through the open top. This type of door was common in the Netherlands in the seventeenth century and appears in Dutch paintings of the period. They were commonly found in Dutch areas of New York and New Jersey (before the American Revolution) and in South Africa.^[3]

The Red and Blue Chair was designed in 1917 by Gerrit Rietveld. It represents one of the first explorations by the De Stijl art movement in three dimensions. It features several Rietveld joints.

The Zig-Zag Chair was designed by Rietveld in 1934. It is a minimalist design without legs, made by 4 flat wooden tiles that are merged in a Z-shape using Dovetail joints. It was designed for the Rietveld Schröder House in Utrecht.

Glazing is a technique employed by painters since the invention of modern oil painting. Early Netherlandish painters in the 15th century were the first to make oil the usual painting medium, and explore the use of layers and glazes, followed by the rest of Northern Europe, and only then Italy.^[4]

Still-life painting as an independent genre or specialty first flourished in the Netherlands in the last quarter of the 16th century, and the English term derives from stilleven: still life, which is a calque, while Romance languages (as well as Greek, Polish, Russian and Turkish) tend to use terms meaning dead nature.

The term "landscape" derives from the Dutch word landschap (and the German Landschaft), which originally meant "region, tract of land" but acquired the artistic connotation, "a picture depicting scenery on land" in the early 16th century. After the fall of the Roman Empire, the tradition of depicting pure landscapes declined and the landscape was seen only as a setting for religious and figural scenes. This tradition continued until the 16th century when artists began to view the landscape as a subject in its own right. The Dutch Golden Age painting of the 17th century saw the dramatic growth of landscape painting, in which many artists specialized, and the development of subtle realist techniques for depicting light and weather.

The Flemish Renaissance painter Pieter Brueghel the Elder chose peasants and their activities as the subject of many paintings. Genre painting flourished in Northern Europe in his wake. Adriaen van Ostade, David Teniers, Aelbert Cuyp, Jan Steen, Johannes Vermeer and Pieter de Hooch were among many painters specializing in genre subjects in the Netherlands during the 17th century. The generally small scale of these artists' paintings was appropriate for their display in the homes of middle class purchasers.

Marine painting began in keeping with medieval Christian art tradition. Such works portrayed the sea only from a bird's eye view, and everything, even the waves, was organized and symmetrical. The viewpoint, symmetry and overall order of these early paintings underlined the organization of the heavenly cosmos from which the earth was viewed. Later Dutch artists such as Hendrick Cornelisz Vroom, Cornelius Claesz, Abraham Storck, Jan Porcellis, Simon de Vlieger, Willem van de Velde the Elder, Willem van de Velde the Younger and Ludolf Bakhuizen developed new methods for painting, often from a horizontal point of view, with a lower horizon and more focus on realism than symmetry.^[5][6]

The term vanitas is most often associated with still life paintings that were popular in seventeenth-century Dutch art, produced by the artists such as Pieter Claesz. Common vanitas symbols included skulls (a reminder of the certainty of death); rotten fruit (decay); bubbles, (brevity of life and suddenness of death); smoke, watches, and hourglasses, (the brevity of life); and musical instruments (the brevity and ephemeral nature of life). Fruit, flowers and butterflies can be interpreted in the same way, while a peeled lemon, as well as the typical accompanying seafood was, like life, visually attractive but with a bitter flavor.

Group portraits were produced in great numbers during the Baroque period, particularly in the Netherlands. Unlike in the rest of Europe, Dutch artists received no commissions from the Calvinist Church which had forbidden such images or from the aristocracy which was virtually non-existent. Instead, commissions came from civic and businesses associations. Dutch painter Frans Hals used fluid brush strokes of vivid color to enliven his group portraits, including those of the civil guard to which he belonged. Rembrandt benefitted greatly from such commissions and from the general appreciation of art by bourgeois clients, who supported portraiture as well as still-life and landscape painting. Notably, the world's first significant art and dealer markets flourished in Holland at that time.

In the 17th century, Dutch painters (especially Frans Hals, Rembrandt, Jan Lievens and Johannes Vermeer) began to create uncommissioned paintings called tronies that focused on the features and/or expressions of people who were not intended to be identifiable. They were conceived more for art's sake than to satisfy conventions. The tronie was a distinctive type of painting, combining elements of the portrait, history, and genre painting. This was usually a half-length of a single figure which concentrated on capturing an unusual mood or expression. The actual identity of the model was not supposed to be important, but they might represent a historical figure and be in exotic or historic costume. In contrast to portraits, "tronies" were painted for the open market. They differ from figurative paintings and religious figures in that they are not restricted to a moral or narrative context. It is, rather, much more an exploration of the spectrum of human physiognomy and expression and the reflection of conceptions of character that are intrinsic to psychology's pre-history.

Rembrandt lighting is a lighting technique that is used in studio portrait photography. It can be achieved using one light and a reflector, or two lights, and is popular because it is capable of producing images which appear both natural and compelling with a minimum of equipment. Rembrandt lighting is characterized by an illuminated triangle under the eye of the subject, on the less illuminated side of the face. It is named for the Dutch painter Rembrandt, who often used this type of lighting in his portrait paintings.

The first known mezzotint was done in Amsterdam in 1642 by Utrecht-born German artist Ludwig von Siegen. He lived in Amsterdam from 1641 to about 1644, when he was supposedly influenced by Rembrandt.^[7][8]

The painter and printmaker Jan van de Velde is often credited to be the inventor of the aquatint technique, in Amsterdam around 1650.^[8]

Pronkstilleven (pronk still life or ostentatious still life) is a type of banquet piece whose distinguishing feature is a quality of ostentation and splendor. These still lifes usually depict one or more especially precious objects. Although the term is a post-17th century invention, this type is characteristic of the second half of the seventeenth century. It was developed in the 1640s in Antwerp from where it spread quickly to the Dutch Republic. Flemish artists such as Frans Snyders and Adriaen van Utrecht started to paint still lifes that emphasized abundance by depicting a diversity of objects, fruits, flowers and dead game, often together with living people and animals. The style was soon adopted by artists from the Dutch Republic.^[9] A leading Dutch representative was Jan Davidsz. de Heem, who spent a long period of his active career in Antwerp and was one of the founders of the style in Holland.^[10][11] Other leading representatives in the Dutch Republic were Abraham van Beyeren, Willem Claeszoon Heda and Willem Kalf.^[9]

Vincent van Gogh's work is most often associated with Post-Impressionism, but his innovative style had a vast influence on 20th-century art and established what would later be known as Expressionism. In his final letter to Theo, Van Gogh stated that, as he had no children, he viewed his paintings as his progeny. Reflecting on this, the British art historian Simon Schama concluded that he "did have a child of course, Expressionism, and many, many heirs."

Dutch graphic artist Maurits Cornelis Escher, usually referred to as M.C. Escher, is known for his often mathematically inspired woodcuts, lithographs, and mezzotints. These feature impossible constructions, explorations of infinity, architecture and tessellations. His special way of thinking and rich graphic work has had a continuous influence in science and art, as well as permeating popular culture. His ideas have been used in fields as diverse as psychology, philosophy, logic, crystallography and topology. His art is based on mathematical principles like tessellations, spherical geometry, the Möbius strip, unusual perspectives, visual paradoxes and illusions, different kinds of symmetries and impossible objects. Gödel, Escher, Bach by Douglas Hofstadter discusses the ideas of self-reference and strange loops, drawing on a wide range of artistic and scientific work, including Escher's art and the music of J. S. Bach, to illustrate ideas behind Gödel's incompleteness theorems.

Miffy (Nijntje) is a small female rabbit in a series of picture books drawn and written by Dutch artist Dick Bruna.

Hardcore or hardcore techno is a subgenre of electronic dance music originating in Europe from the emergent raves in the 1990s. It was initially designed at Rotterdam in Netherlands, derived from techno.^[12]

Hardstyle is an electronic dance genre mixing influences from hardtechno and hardcore. Hardstyle was influenced by gabber. Hardstyle has its origins in the Netherlands where artists like DJ Zany, Lady Dana, DJ Isaac, DJ Pavo, DJ Luna and The Prophet, who produced hardcore, started experimenting while playing their hardcore records.

Through history, carrots were not always orange. They were black, purple, white, brown, red and yellow. Probably orange too, but this was not the dominant colour. Orange-coloured carrots probably first appeared in the Netherlands in the 16th century,^[13] bred by farmers in Hoorn. They succeeded by cross-breeding pale yellow with red carrots. It is more likely that Dutch horticulturists actually found an orange rooted mutant variety and then worked on its development through selective breeding to make the plant consistent. Through successive hybridisation the orange colour intensified. This was developed to become the dominant species across the world, a sweet orange.

The Belle de Boskoop is an apple cultivar which, as its name suggests, originated in Boskoop, where it began as a chance seedling in 1856. There are many variants: Boskoop red, yellow or green. This rustic apple is firm, tart and fragrant. Greenish-gray tinged with red, the apple stands up well to cooking. Generally Boskoop varieties are very high in acid content and can contain more than four times the vitamin C of 'Granny Smith' or 'Golden Delicious'.^[14]

The Karmijn de Sonnaville is a variety of apple bred by Piet de Sonnaville, working in Wageningen in 1949. It is a cross of Cox's Orange Pippin and Jonathan, and was first grown commercially beginning in 1971. It is high both in sugars (including some sucrose) and acidity. It is a triploid, and hence needs good pollination, and can be difficult to grow. It also suffers from fruit russet, which can be severe. In Manhart's book, "apples for the 21st century", Karmijn de Sonnaville is tipped as a possible success for the future. Karmijn de Sonnaville is not widely grown in large quantities, but in Ireland, at The Apple Farm, 8 acres (3.2 ha) it is grown for fresh sale and juice-making, for which the variety is well suited.

The Elstar apple is an apple cultivar that was first developed in the Netherlands in the 1950s by crossing Golden Delicious and Ingrid Marie apples. It quickly became popular, especially in Europe and was first introduced to America in 1972.^[15] It remains popular in Continental Europe. The Elstar is a medium-sized apple whose skin is mostly red with yellow showing. The flesh is white, and has a soft, crispy texture. It may be used for cooking and is especially good for making apple sauce. In general, however, it is used in desserts due to its sweet flavour.

The Groasis Waterboxx is a device designed to help grow trees in dry areas. It was developed by former flower exporter Pieter Hoff, and won Popular Science's "Green Tech Best of What's New" Innovation of the year award for 2010.

Triangulation had first emerged as a map-making method in the mid-sixteenth century when the Dutch-Frisian mathematician Gemma Frisius set out the idea in his Libellus de locorum describendorum ratione (Booklet concerning a way of describing places).^[16][17] Dutch cartographer Jacob van Deventer was among the first to make systematic use of triangulation, the technique whose theory was described by Gemma Frisius in his 1533 book.

The modern systematic use of triangulation networks stems from the work of the Dutch mathematician Willebrord Snell (born Willebrord Snel van Royen), who in 1615 surveyed the distance from Alkmaar to Bergen op Zoom, approximately 70 miles (110 kilometres), using a chain of quadrangles containing 33 triangles in all^[18][19] – a feat celebrated in the title of his book Eratosthenes Batavus (The Dutch Eratosthenes), published in 1617.

The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant course, known as rhumb lines or loxodromes, as straight segments which conserve the angles with the meridians.^[20]

Flemish geographer and cartographer Abraham Ortelius generally recognized as the creator of the world's first modern atlas, the Theatrum Orbis Terrarum (Theatre of the World). Ortelius's Theatrum Orbis Terrarum is considered the first true atlas in the modern sense: a collection of uniform map sheets and sustaining text bound to form a book for which copper printing plates were specifically engraved. It is sometimes referred to as the summary of sixteenth-century cartography.^{[21][22][23][24]}

The first printed atlas of nautical charts (De Spieghel der Zeevaerdt or The Mirror of Navigation / The Mariner's Mirror) was produced by Lucas Janszoon Waghenaer in Leiden. This atlas was the first attempt to systematically codify nautical maps. This chart-book combined an atlas of nautical charts and sailing directions with instructions for navigation on the western and north-western coastal waters of Europe. It was the first of its kind in the history of maritime cartography, and was an immediate success. The English translation of Waghenaer's work was published in 1588 and became so popular that any volume of sea charts soon became known as a "waggoner", the Anglicized form of Waghenaer's surname.^[25][26][27]

The constellations around the South Pole were not observable from north of the equator, by Babylonians, Greeks, Chinese or Arabs. The modern constellations in this region were defined during the Age of Exploration, notably by Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman at the end of sixteenth century. These twelve Dutch-created southern constellations represented flora and fauna of the East Indies and Madagascar. They were depicted by Johann Bayer in his star atlas Uranometria of 1603.^[28] Several more were created by Nicolas Louis de Lacaille in his star catalogue, published in 1756.^[29] By the end of the Ming dynasty, Xu Guangqi introduced 23 asterisms of the southern sky based on the knowledge of western star charts.^[30] These asterisms have since been incorporated into the traditional Chinese star maps. Among the IAU's 88 modern constellations, there are 15 Dutch-created constellations (including Apus, Camelopardalis, Chamaeleon, Columba, Dorado, Grus, Hydrus, Indus, Monoceros, Musca, Pavo, Phoenix, Triangulum Australe, Tucana and Volans).

The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912. Because Wegener's publications were widely available in German and English and because he adduced geological support for the idea, he is credited by most geologists as the first to recognize the possibility of continental drift. During the 1960s geophysical and geological evidence for seafloor spreading at mid-oceanic ridges established continental drift as the standard theory or continental origin and an ongoing global mechanism.

While making a coloured liquid for a thermometer, Cornelis Drebbel dropped a flask of Aqua regia on a tin window sill, and discovered that stannous chloride makes the color of carmine much brighter and more durable. Though Drebbel himself never made much from his work, his daughters Anna and Catharina and his sons-in-law Abraham and Johannes Sibertus Kuffler set up a successful dye works. One was set up in 1643 in Bow, London, and the resulting color was called bow dye.

Dutch chemical company DSM invented and patented the Dyneema in 1979. Dyneema fibres have been in commercial production since 1990 at their plant at Heerlen. These fibers are manufactured by means of a gel-spinning process that combines extreme strength with incredible softness. Dyneema fibres, based on ultra-high-molecular-weight polyethylene (UHMWPE), is used in many applications in markets such as life protection, shipping, fishing, offshore, sailing, medical and textiles.

In 1962 Philips invented the compact audio cassette medium for audio storage, introducing it in Europe in August 1963 (at the Berlin Radio Show) and in the United States (under the Norelco brand) in November 1964, with the trademark name Compact Cassette.^{[31][32][33][34][35]}

Laserdisc technology, using a transparent disc,^[36] was invented by David Paul Gregg in 1958 (and patented in 1961 and 1990).^[37] By 1969, Philips developed a videodisc in reflective mode, which has great advantages over the transparent mode. MCA and Philips decided to join forces. They first publicly demonstrated the videodisc in 1972. Laserdisc entered the market in Atlanta, on 15 December 1978, two years after the VHS VCR and four years before the CD, which is based on Laserdisc technology. Philips produced the players and MCA made the discs.

The compact disc was jointly developed by Philips (Joop Sinjou) and Sony (Toshitada Doi). In the early 1970s, Philips' researchers started experiments with "audio-only" optical discs, and at the end of the 1970s, Philips, Sony, and other companies presented prototypes of digital audio discs.

Bluetooth, a low-energy, peer-to-peer wireless technology was originally developed by Dutch electrical engineer Jaap Haartsen and Swedish engineer Sven Mattisson in the 1990s, working at Ericsson in Lund, Sweden. It became a global standard of short distance wireless connection.

In 1991, NCR Corporation/AT&T Corporation invented the precursor to 802.11 in Nieuwegein. Dutch electrical engineer Vic Hayes chaired IEEE 802.11 committee for 10 years, which was set up in 1990 to establish a wireless networking standard. He has been called the father of Wi-Fi (the brand name for products using IEEE 802.11 standards) for his work on IEEE 802.11 (802.11a & 802.11b) standard in 1997.

The DVD optical disc storage format was invented and developed by Philips and Sony in 1995.

Ambilight, short for "ambient lighting", is a lighting system for televisions developed by Philips in 2002.

Philips and Sony in 1997 and 2006 respectively, launched the Blu-ray video recording/playback standard.

Dijkstra's algorithm, conceived by Dutch computer scientist Edsger Dijkstra in 1956 and published in 1959, is a graph search algorithm that solves the single-source shortest path problem for a graph with non-negative edge path costs, producing a shortest path tree. Dijkstra's algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it finds all of the shortest paths from the source to all destinations. This algorithm is often used in routing and as a subroutine in other graph algorithms.

Dijkstra's algorithm is considered as one of the most popular algorithms in computer science. It is also widely used in the fields of artificial intelligence, operational research/operations research, network routing, network analysis, and transportation engineering.

The academic study of concurrent programming started in the 1960s, with Edsger Dijkstra (1965) credited with being the first paper in this field, identifying and solving mutual exclusion.^[38] A pioneer in the field of concurrent computing, Per Brinch Hansen considers Dijkstra's Cooperating Sequential Processes (1965) to be the first classic paper in concurrent programming.^[39]

In computer science, the shunting-yard algorithm is a method for parsing mathematical expressions specified in infix notation. It can be used to produce output in Reverse Polish notation (RPN) or as an abstract syntax tree (AST). The algorithm was invented by Edsger Dijkstra and named the "shunting yard" algorithm because its operation resembles that of a railroad shunting yard. Dijkstra first described the Shunting Yard Algorithm in the Mathematisch Centrum report.

In 1963/64, during an extended stay at SLAC, Dutch theoretical physicist Martinus Veltman designed the computer program Schoonschip for symbolic manipulation of mathematical equations, which is now considered the very first computer algebra system.

In computer science, mutual exclusion refers to the requirement of ensuring that no two concurrent processes are in their critical section at the same time; it is a basic requirement in concurrency control, to prevent race conditions. The requirement of mutual exclusion was first identified and solved by Edsger W. Dijkstra in his seminal 1965 paper titled Solution of a problem in concurrent programming control,^[40][41] and is credited as the first topic in the study of concurrent algorithms.^[38]

The semaphore concept was invented by Dijkstra in 1965 and the concept has found widespread use in a variety of operating systems.^[42]

In computer science, the sleeping barber problem is a classic inter-process communication and synchronization problem between multiple operating system processes. The problem is analogous to that of keeping a barber working when there are customers, resting when there are none and doing so in an orderly manner. The sleeping barber problem was introduced by Edsger Dijkstra in 1965.^[42]

The Banker's algorithm is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra that tests for safety by simulating the allocation of predetermined maximum possible amounts of all resources, and then makes an "s-state" check to test for possible deadlock conditions for all other pending activities, before deciding whether allocation should be allowed to continue. The algorithm was developed in the design process for the THE multiprogramming system and originally described (in Dutch) in EWD108.^[43] The name is by analogy with the way that bankers account for liquidity constraints.

In computer science, the dining philosophers problem is an example problem often used in concurrent algorithm design to illustrate synchronization issues and techniques for resolving them. It was originally formulated in 1965 by Edsger Dijkstra as a student exam exercise, presented in terms of computers competing for access to tape drive peripherals. Soon after, Tony Hoare gave the problem its present formulation.^[44][45]

Dekker's algorithm is the first known correct solution to the mutual exclusion problem in concurrent programming. Dijkstra attributed the solution to Dutch mathematician Theodorus Dekker in his manuscript on cooperating sequential processes. It allows two threads to share a single-use resource without conflict, using only shared memory for communication. It is also the first published software-only, two-process mutual exclusion algorithm.

The THE multiprogramming system was a computer operating system designed by a team led by Edsger W. Dijkstra, described in monographs in 1965–66^[46] and published in 1968.^[47]

Van Wijngaarden grammar (also vW-grammar or W-grammar) is a two-level grammar that provides a technique to define potentially infinite context-free grammars in a finite number of rules. The formalism was invented by Adriaan van Wijngaarden to rigorously define some syntactic restrictions that previously had to be formulated in natural language, despite their formal content. Typical applications are the treatment of gender and number in natural language syntax and the well-definedness of identifiers in programming languages. The technique was used and developed in the definition of the programming language ALGOL 68. It is an example of the larger class of affix grammars.

In 1968, computer programming was in a state of crisis. Dijkstra was one of a small group of academics and industrial programmers who advocated a new programming style to improve the quality of programs. Dijkstra coined the phrase "structured programming" and during the 1970s this became the new programming orthodoxy. Structured programming is often regarded as "goto-less programming".

An EPROM or erasable programmable read only memory, is a type of memory chip that retains its data when its power supply is switched off. Development of the EPROM memory cell started with investigation of faulty integrated circuits where the gate connections of transistors had broken. Stored charge on these isolated gates changed their properties. The EPROM was invented by the Amsterdam-born Israeli electrical engineer Dov Frohman in 1971, who was awarded US patent 3660819^[48] in 1972.

Self-stabilization is a concept of fault-tolerance in distributed computing. A distributed system that is self-stabilizing will end up in a correct state no matter what state it is initialized with. That correct state is reached after a finite number of execution steps.^[49]

Predicate transformer semantics were introduced by Dijkstra in his seminal paper "Guarded commands, nondeterminacy and formal derivation of programs".

The Guarded Command Language (GCL) is a language defined by Edsger Dijkstra for predicate transformer semantics.^[50] It combines programming concepts in a compact way, before the program is written in some practical programming language.

A Van Emde Boas tree (or Van Emde Boas priority queue, also known as a vEB tree, is a tree data structure which implements an associative array with m-bit integer keys. The vEB tree was invented by a team led by Dutch computer scientist Peter van Emde Boas in 1975.^[51]

ABC is an imperative general-purpose programming language and programming environment developed at CWI, Netherlands by Leo Geurts, Lambert Meertens, and Steven Pemberton. It is interactive, structured, high-level, and intended to be used instead of BASIC, Pascal, or AWK. It is not meant to be a systems-programming language but is intended for teaching or prototyping.

The language had a major influence on the design of the Python programming language (as a counterexample); Guido van Rossum, who developed Python, previously worked for several years on the ABC system in the early 1980s.^[52][53]

The Dijkstra–Scholten algorithm (named after Edsger W. Dijkstra and Carel S. Scholten) is an algorithm for detecting termination in a distributed system.^[54][55] The algorithm was proposed by Dijkstra and Scholten in 1980.^[56]

Smoothsort^[57] is a comparison-based sorting algorithm. It is a variation of heapsort developed by Edsger Dijkstra in 1981. Like heapsort, smoothsort's upper bound is O(n log n). The advantage of smoothsort is that it comes closer to O(n) time if the input is already sorted to some degree, whereas heapsort averages O(n log n) regardless of the initial sorted state.

The Amsterdam Compiler Kit (ACK) is a fast, lightweight and retargetable compiler suite and toolchain developed by Andrew Tanenbaum and Ceriel Jacobs at the Vrije Universiteit in Amsterdam. It is MINIX's native toolchain. The ACK was originally closed-source software (that allowed binaries to be distributed for MINIX as a special case), but in April 2003 it was released under an open-source BSD license. It has frontends for programming languages C, Pascal, Modula-2, Occam, and BASIC. The ACK's notability stems from the fact that in the early 1980s it was one of the first portable compilation systems designed to support multiple source languages and target platforms.^[58]

EFM (Eight-to-Fourteen Modulation) was invented by Dutch electrical engineer Kees A. Schouhamer Immink in 1985. EFM is a data encoding technique – formally, a channel code – used by CDs, laserdiscs and pre-Hi-MD MiniDiscs.

MINIX (from "mini-Unix") is a Unix-like computer operating system based on a microkernel architecture. Early versions of MINIX were created by Andrew S. Tanenbaum for educational purposes. Starting with MINIX 3, the primary aim of development shifted from education to the creation of a highly reliable and self-healing microkernel OS. MINIX is now developed as open-source software. MINIX was first released in 1987, with its complete source code made available to universities for study in courses and research. It has been free and open-source software since it was re-licensed under the BSD license in April 2000. Tanenbaum created MINIX at the Vrije Universiteit in Amsterdam to exemplify the principles conveyed in his textbook, Operating Systems: Design and Implementation (1987), that Linus Torvalds described as "the book that launched me to new heights".

Amoeba is a distributed operating system developed by Andrew S. Tanenbaum and others at the Vrije Universiteit in Amsterdam. The aim of the Amoeba project was to build a timesharing system that makes an entire network of computers appear to the user as a single machine. The Python programming language was originally developed for this platform.^[59]

Python is a widely used general-purpose, high-level programming language.^[60][61] Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C++ or Java.^[62][63] The language provides constructs intended to enable clear programs on both a small and large scale. Python supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles. It features a dynamic type system and automatic memory management and has a large and comprehensive standard library.

Python was conceived in the late 1980s and its implementation was started in December 1989 by Guido van Rossum at CWI in the Netherlands as a successor to the ABC language (itself inspired by SETL) capable of exception handling and interfacing with the Amoeba operating system. Van Rossum is Python's principal author, and his continuing central role in deciding the direction of Python is reflected in the title given to him by the Python community, benevolent dictator for life (BDFL).

Vim is a text editor written by the Dutch free software programmer Bram Moolenaar and first released publicly in 1991. Based on the Vi editor common to Unix-like systems, Vim carefully separated the user interface from editing functions.^{[citation needed]} This allowed it to be used both from a command line interface and as a standalone application in a graphical user interface.^{[citation needed]}

Blender is a professional free and open-source 3D computer graphics software product used for creating animated films, visual effects, art, 3D printed models, interactive 3D applications and video games. Blender's features include 3D modeling, UV unwrapping, texturing, raster graphics editing, rigging and skinning, fluid and smoke simulation, particle simulation, soft body simulation, digital sculpting, computer animation, match moving, camera tracking, rendering, video editing and compositing. Alongside the modelling features it also has an integrated game engine. Blender has been successfully used in the media industry in several parts of the world including Argentina, Australia, Belgium, Brazil, Russia, Sweden, and the United States.

The Dutch animation studio Neo Geo and Not a Number Technologies (NaN) developed Blender as an in-house application, with the primary author being Ton Roosendaal. The name Blender was inspired by a song by Yello, from the album Baby.^[64]

EFMPlus is the channel code used in DVDs and SACDs, a more efficient successor to EFM used in CDs. It was created by Dutch electrical engineer Kees A. Schouhamer Immink, who also designed EFM. It is 6% less efficient than Toshiba's SD code, which resulted in a capacity of 4.7 gigabytes instead of SD's original 5 GB. The advantage of EFMPlus is its superior resilience against disc damage such as scratches and fingerprints.

A Dutch auction is also known as an open descending price auction. Named after the famous auctions of Dutch tulip bulbs in the 17th century, it is based on a pricing system devised by Nobel Prize–winning economist William Vickrey. In the traditional Dutch auction, the auctioneer begins with a high asking price which is lowered until some participant is willing to accept the auctioneer's price. The winning participant pays the last announced price. Dutch auction is also sometimes used to describe online auctions where several identical goods are sold simultaneously to an equal number of high bidders. In addition to cut flower sales in the Netherlands, Dutch auctions have also been used for perishable commodities such as fish and tobacco.

In 1609, Isaac Le Maire filed a petition against the VOC, marking the first recorded expression of shareholder
