William Joseph and Ethel Fountain Hussey family of Ann Arbor, Michigan. Correspondence, diaries, scrapbooks, photographs and other materials relating especially to Hussey's activities as professor of astronomy and director of the astronomical observatory at the University of Michigan, including his scientific visits to South America and South Africa.

The Hussey family collection divides between the papers of William Joseph Hussey and his wife Ethel Fountain Hussey. The William Joseph Hussey papers includes correspondence, papers relating to his astronomical work, travels abroad, and affairs at the universities where Hussey held appointments, particularly The University of Michigan. Of interest are two letterpress books, two University of Michigan student notebooks containing notes on John William Langley's course in physics and notes on mathematics, account books, scrapbooks, and diaries of Argentina and South Africa travels and activities in The University of Michigan Observatory.

The papers of Ethel Fountain Hussey include correspondence, diaries, manuscript drafts of articles, and subject files relating to her organizational activities, her early work with the Michigan League and with the Association of Collegiate Alumnae. Some of the couple's correspondents included James B. Angell, Levi L. Barbour, Luther Burbank, Marion L. Burton, William W. Campbell, William L. Clements, Ralph H. Curtiss, David Starr Jordan, Robert P. Lamont.

Wife of University of Michigan President, James B. Angell and member of Collegiate Sorosis. Angell served as the president of the Women’s Foreign Missionary Society of Congressional Church. The Daughters of the American Revolution Ann Arbor chapter has been named after Sarah Caswell Angell. Collection includes Sarah Caswell Angell's diaries and letters concerning Ann Arbor and the University of Michigan life, her church activities, social life, the Daughters of the American Revolution activities, family affairs, and travels to Turkey and China.

The Sarah Caswell Angell papers primarily consist of her her diaries and correspondence, as well as records of her father, Alexis Caswell, and other family members. While much or the correspondence is personal in nature (specifically to her friends and family), the collection includes a folder with materials focused on her work with the Chicago World’s Fair as well as the Ann Arbor chapter of the Daughters of the American Revolution. The diaries included within the collection document some of Angell’s daily activities as well as describe her trips to China and Turkey with her husband.

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.
