Theophil Henry Hildebrandt Papers, 1887-1978 (majority within 1930-1960)

7 linear feet

Mathematician, professor of mathematics at the University of Michigan. Correspondence and other papers relating to professional and family matters, to his association with the Bethlehem Church in Ann Arbor, and to his involvement with the American Mathematical Society, especially regarding the controversy over loyalty oaths in the 1950s; also letters from family members, notably sister Martha, a school teacher, who comments on her career and her life as a single woman; and letters from son Paul during World War II; and photographs.

The papers of T.H. Hildebrandt consist of seven linear feet of materials spanning the years 1887 to 1978. The bulk of the collection falls between the years 1930 and 1960. The papers have been arranged in ten series: Biographical Material, Bethlehem Church, Compositions, Correspondence, Lectures, Notes, Organizations, Universities, Writings, and Visual Materials.

As Hildebrandt was fairly well known in his field, he corresponded with other eminent mathematicians of his time, including Eliakim Hostings Moore (with whom he had studied) and Maurice Frechet. The Hildebrandt papers are also valuable for other topics: the development of mathematical ideas and the various pressures placed on academics during the Cold War to name both two examples.
