Collections : [University of Michigan Bentley Historical Library]

Ann Arbor, Michigan, family. Correspondence, other papers and photographs of Arthur Brown, Ann Arbor attorney and mayor, and officer and director of the Washtenaw Abstract Company; also papers of his wife, Cora Pulcipher Brown, largely concerning work with Americanism Committee of the Daughters of the American Revolution during World War II.

The Brown family collection is unfortunately a fragment of materials with very few of the papers created by either Arthur or Cora Brown surviving. What remains relate almost exclusively to the legal career of Arthur Brown, in particular to his service to various persons as a collector of bad debts, and to Cora Brown's work with the Americanism Committee of the Daughters of the American Revolution during World War II.

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.
