Person: Wilder, Raymond Louis
Raymond Wilder was an American mathematician who worked in topology as well as producing works on philosophy.
Mathematical Profile (Excerpt):
 Wilder then taught mathematics at Brown during 192021 while studying for his master's degree in actuarial mathematics which he received in 1921.
 Wilder moved to the University of Texas in 1921 where again he was appointed as an instructor while he worked for his doctorate.
 After Wilder persuaded Moore to let him take the course, Moore proceeded to ignore him until he solved one of the hardest problems Moore posed to the class.
 Wilder gave up his plans to study actuarial mathematics and became Moore's research student.
 He suggested Wilder write up the solution to the problem for his doctorate which indeed he did, becoming Moore's first Texas doctorate in 1923 with his dissertation Concerning Continuous Curves.
 Wilder's thesis contained a new approach to the Schönflies programme.
 He continued to undertake research with this aim and in 1930, in A converse of the JordanBrouwer separation theorem in three dimensions, Wilder showed that a subset of Euclidean 3space whose complementary domains satisfied certain homology conditions was a 2sphere.
 Wilder's hostility to mindless patriotism and his predilection for liberal thought accompanied him throughout his life.
 The initial phase of Wilder's research on the Schönflies programme, which we described above, was in in settheoretic topology and lasted until around 1930.
 The final three chapters of the book discuss Wilder's contributions in the theory of positional topological invariants.
 It was around the time that Wilder published the first edition of Topology of Manifolds that his research interests underwent a major change.
 Wilder's ideas continued to develop along the lines of cultural anthropology.
 In 1981 Wilder published another major text Mathematics as a cultural system which has a similar title to the talk he gave to the International Congress of Mathematicians thirty years earlier.
 After Wilder retired from the University of Michigan in 1967 he moved to the University of California at Santa Barbara.
 Wilder contributed much to American mathematics.
 Wilder played a major role in the Mathematical Association of America being its president during 196566.
Born 3 November 1896, Palmer, Massachusetts, USA. Died 7 July 1982, Santa Barbara, California, USA.
