Dirk van Dalen's biography studies the fascinating life of the famous
Dutch mathematician and philosopher Luitzen Egbertus Jan Brouwer.
Brouwer belonged to a special class of genius; complex and often
controversial and gifted with a deep intuition, he had an unparalleled
access to the secrets and intricacies of mathematics. Most
mathematicians remember L.E.J. Brouwer from his scientific breakthroughs
in the young subject of topology and for the famous Brouwer fixed point
theorem. Brouwer's main interest, however, was in the foundation of
mathematics which led him to introduce, and then consolidate,
constructive methods under the name 'intuitionism'. This made him one of
the main protagonists in the 'foundation crisis' of mathematics. As a
confirmed internationalist, he also got entangled in the interbellum
struggle for the ending of the boycott of German and Austrian
scientists. This time during the twentieth century was turbulent;
nationalist resentment and friction between formalism and intuitionism
led to the Mathematische Annalen conflict ('The war of the frogs and the
mice'). It was here that Brouwer played a pivotal role. The present
biography is an updated revision of the earlier two volume biography in
one single book. It appeals to mathematicians and anybody interested in
the history of mathematics in the first half of the twentieth century.
