The foundation was completed in the thesis of van Dantzig ...; topological groups, rings, fields, and linear spaces are there defined, and their basic properties are established.

As the head of the Department of Mathematical Statistics, Van Dantzig was instrumental in enhancing research and fostering consultancy, gaining widespread recognition both nationally and internationally.

[5] Originally working on topics in differential geometry and topology, after World War II he focused on probability, emphasizing the applicability to statistical hypothesis testing.

Additionally, Van Dantzig held the position of Visiting Professor at the University of California, Berkeley in 1951 and spent time working at the National Bureau of Standards in Washington, D.C.[5] In response to the North Sea flood of 1953, the Dutch Government established the Delta Committee, and asked Van Dantzig to develop a mathematical approach to formulate and solve the economic cost-benefit decision model concerning optimal dike height problems in connection with the Delta Works.

It proved the starting point of a life-long symbiosis of pupil and master in mathematics, metamathematics and significs... Media related to David van Dantzig at Wikimedia Commons
