He then studied for a doctorate in hydrodynamics, but then abandoned the area.
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 joined the Nationaal Luchtvaartlaboratorium in 1945 and went with a group to England the following year to learn about new technologies that had been developed there during World World War 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 (Military Cross) 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. 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 Military Cross in 1961, and remained in that post for the next twenty years.
