Person: Zaanen, Adriaan Cornelis

Adriaan Cornelis Zaanen was a Dutch mathematician who worked mainly in analysis.

His parents were Pieter Zaanen and Ariaantje de Bruin.
Aad Zaanen was brought up in Rotterdam where he attended the secondary school (hogere burgerschool).
After completing a first degree in Mathematics and Physics in 1935, Zaanen continued his studies at Leiden undertaking research with Johannes Droste as his advisor.
After completing his doctoral studies, Zaanen became a secondary school teacher in Rotterdam, teaching mathematics.
After three years in Indonesia, Zaanen returned to the Netherlands where he was appointed as Professor of Analysis in the Technical University of Delft in 1950.
On the other hand it reflects Zaanen's mathematical career over more than forty years.
During this period Zaanen made essential contributions to several parts of mathematics, mainly in functional analysis, integration theory and Riesz space theory.
Through these four decades Zaanen established his own school of thought with its centre of gravity in Leiden and with its representatives abroad.
When he retired Zaanen gave the address Looking back: farewell lecture at the University of Leiden on 3 December 1982.
An important contribution by Zaanen was the texts that he published.
In 1967 Zaanen published a completely revised and extended edition of An introduction to the theory of integration under the title Integration.
In 1989 Zaanen published Continuity, integration and Fourier theory.
