Moïse taught at the
University of Michigan from 1947 to 1960. He was James B. Conant Professor of education and mathematics at
Harvard University from 1960 to 1971. He held a Distinguished Professorship at
Queens College, City University of New York from 1971 to 1987. Moïse started working on the topology of
3-manifolds while at the
University of Michigan. During 1949–1951 he held an appointment at the
Institute for Advanced Study during which he proved
Moise's theorem that every 3-manifold can be
triangulated in an essentially unique way. Moïse joined the
School Mathematics Study Group when it started in 1958, as a member of the geometry writing team. The team produced several course outlines and sample pages for a 10th grade
geometry course, and then Moïse and Floyd L. Downs wrote a geometry textbook, based on the team's approach, that was published in 1964. The textbook used metric postulates instead of
Euclid's postulates, a controversial approach supported by some mathematicians such as
Saunders Mac Lane but opposed by others such as Alexander Wittenberg and
Morris Kline. Moïse was a president of the
Mathematical Association of America, a vice-president of the
American Mathematical Society, a Fellow of the
American Academy of Arts and Sciences, and was on the executive committee of the
International Commission on Mathematical Instruction. Moïse retired from Queens College in 1987 and started a second career studying 19th century
English poetry. He had six short notes of
literary criticism published. Moise died in
New York City on December 18, 1998, aged 79. ==Selected publications==
