 Brouwer’s principal (intuitionistic) students were Maurits Belinfante, Arend Heyting, and Johan de Iongh; Heyting, in turn, was the teacher of Anne Troelstra and Dirk van Dalen, and de Iongh of Wim Veldman. Brouwer’s classes were also attended by Max Euwe, later to become world chess champion, who published a game-theoretical paper on chess from the intuitionistic point of view (Euwe, 1929), and who would much later deliver Brouwer’s funeral speech. Among Brouwer’s assistants were Heyting, Hans Freudenthal, Karl Menger, and Witold Hurewicz, the latter two of whom were not intuitionistically inclined. The most influential supporter of Brouwer’s intuitionism outside the Netherlands at the time was, for a number of years, Hermann Weyl (whose adaptation of intuitionistic analysis was not wholly coherent); also Husserl’s student Oskar Becker should be mentioned.
