  • Adriaan van Wijngaarden was an important mathematician and computer scientist who is considered by many to have been the founding father of informatica in the Netherlands. Even though he was trained as an engineer, van Wijngaarden would emphasize and promote the mathematical aspects of computing, first in numerical analysis, then in programming languages and finally in design principles of programming languages. His education was in mechanical engineering, for which he received a degree from Delft University of Technology in 1939. He then studied for a doctorate in hydrodynamics, but then abandoned the area. He joined the Nationaal Luchtvaart Laboratorium in 1945 and went with a group to England the following year to learn about new technologies that had been developed there during World War II. Van Wijngaarden was intrigued by the new idea of automatic computing, and on 1 January 1947 he became the head of the Computing Department of the brand-new Mathematisch Centrum (MC) in Amsterdam. He then made further visits to England and the United States, gathering ideas for the construction of the first Dutch computer, the ARRA, an electromechanical construction first demonstrated in 1952. In that same year, van Wijngaarden hired Edsger Dijkstra, and they worked on software for the ARRA. While visiting Edinburgh in 1958, van Wijngaarden was seriously injured in an automobile accident in which his wife was killed. After he recovered, he focused more on programming language research, and was one of the designers of the original ALGOL, and later ALGOL 68, for which he developed a two-level type of grammar that came be known as van Wijngaarden grammars. He became the director of the MC in 1961, and remained in that post for the next twenty years. "Aad" was in many ways an original human being: he was known for having dropped a plausible dissertation in 1945 simply because "it lacked beauty. " He used a small "at" (@) sign as his personal mark. Through his work as leader of the ALGOL 68 committee, he made a deep (though belatedly recognized) contribution to the field of programming language design, definition and description.

  • Adriaan van Wijngaarden (Rotterdam, 2 de noviembre de 1916 – 7 de febrero de 1987) fue un importante matemático y científico informático, quien es considerado por varios como el padre de la informática (ciencia computacional) en Holanda. Incluso, aunque fue entrenado como Ingeniero, van Wijngaarden enfatizó en promover los aspectos matemáticos de la computación, primeramente en análisis numérico, luego en lenguajes de programación y finalmente en el diseño de los principios de los lenguajes de programación.

Van Wijngaarden studeerde werktuigbouwkunde aan de Technische Hogeschool Delft, waar bij in 1939 afstudeerde. Hij vervolgde met een promotie onderzoek in de mechanica (cum laude, 1945). In 1945 trad hij in dienst van het Nationaal Luchtvaart Laboratorium. Vanaf 1947 was hij hoofd van de Rekenafdeling van het Mathematisch Centrum in Amsterdam en ontwikkelde de Van Wijngaardengrammatica, een variant van de contextvrije grammatica. Hij was tevens hoofd van het comité dat de programmeertaal Algol-68 ontwikkelde.

Muito embora ele tenha sido treinado como engenheiro, van Wijngaarden iria dar ênfase em promover os aspectos matemáticos da computação, primeiramente na área de análise numérica, e depois no campo das linguagens de programação e finalmente no projeto de princípios de linguagens de programação. Sua formação foi em engenharia mecânica, para o qual ele obteve o grau da Delft University of Technology em 1939. Ele então estudou por um doutorado em hidrodinâmica, mas depois abandonou a área. Ele se juntou ao Nationaal Luchtvaart Laboratorium em 1945 e foi com um grupo para a Inglaterra no ano seguinte para aprender sobre novas tecnologias, que tinham sido desenvolvido lá durante a II Guerra Mundial. Wijngaarden ficou intrigado com a nova idéia da computação, e em 1 de janeiro de 1947 ele se tornou o chefe do Departamento de Informática do novíssimo Mathematisch Centrum (MC), em Amsterdã. Ele então fez outras visitas à Inglaterra e os Estados Unidos, reunindo ideias para a construção do primeiro computador holandês, o ARRA, uma construção eletromecânica demonstrado pela primeira vez em 1952. Nesse mesmo ano, van Wijngaarden contratou Edsger Dijkstra, e eles trabalharam em softwares para o ARRA. Ao visitar Edimburgo, em 1958, van Wijngaarden ficou gravemente ferido em um acidente automobilístico no qual sua esposa foi morta. Depois de ter recuperado, ele se concentrou mais na pesquisa das linguagens de programação, e foi um dos criadores do original ALGOL e depois da ALGOL 68, para a qual ele desenvolveu um tipo de gramática de dois níveis que veio ser conhecido como gramáticas de van Wijngaarden. Ele se tornou o diretor da MC em 1961, e permaneceu no cargo durante os próximos vinte anos. "Aad" foi, em muitos aspectos uma figura humana singular: ele era conhecido por ter desistido de uma tese plausível, em 1945, simplesmente porque "não tinha beleza". Ele usou um pequeno sinal de arroba (@) como sua marca pessoal. Através de seu trabalho como líder da comissão de ALGOL 68, ele fez uma profunda (embora tardiamente reconhecida) contribuição para o campo do projeto, definição e descrição das linguagens de programação.
