A druggist by training, William Denslow became interested in botany as a means of combating tuberculosis through outdoor exercise. As his interests developed, Denslow amassed an herbarium that included between 11,000 and 15,000 specimens, including both American and European species.

The Denslow collection consists of a single volume of manuscripts, chiefly letters, collected from significant botanists and other individuals, including William Henry Brewer, Mordecai Cubitt Cooke, Asa Gray, Isaac Hollister Hall, Thomas P. James, Horace Mann, Edward Sylvester Morse, Charles Horton Peck, George Edward Post, Frederick Ward Putnam, George Thurber, and John Torrey.

Charles A. Goessmann, ca.1890

German-born agricultural chemist, professor of Chemistry at the University of Massachusetts Amherst when it was known as Massachusetts Agricultural College, and President of the Association of Official Agricultural Chemists and the American Chemical Society who made several important contributions in nineteenth century chemistry and held at least four patents.

The Goessman collection includes correspondence (mostly professional), some with presidents of Massachusetts Agricultural College, William Smith Clark (1826-1886) and Henry Hill Goodell (1839-1905). Also contains handwritten drafts of addresses and articles, his dissertation, printed versions of published writings, handwritten lecture notes, class records, proposed college curricula, notes taken by students, handwritten research notes, newsclippings and offprints utilized in research, and biographical materials.

Includes records of services provided, such as repairing, cleaning, painting and varnishing chaises; providing wheels, springs, waterhooks, whippletrees, bellybands, and carpet; and mending reins and harnesses. Also contains lists of customers (including many prominent families from the town) and records of cash transactions.

Generations of the Bates and Church families based in North Amherst and Ashfield, Massachusetts. Papers include deeds, a will, correspondence, account books (recording day-to-day expenditures on food, clothing, postage, housekeeping supplies, and laborer’s wages), diaries, an oral history, photographs, genealogical notes, and memorabilia related to the family.

William Smith Clark

Born in Ashfield, Massachusetts, in 1826, William Smith Clark graduated from Amherst College in 1848 and went on to teach the natural sciences at Williston Seminary until 1850, when he continued his education abroad, studying chemistry and botany at the University of Goettingen, earning his Ph.D in 1852. From 1852 to 1867 he was a member of Amherst College’s faculty as a Professor of Chemistry, Botany, and Zoology. As a leading citizen of Amherst, Clark was a strong advocate for the establishment of the new agricultural college, becoming one of the founding members of the college’s faculty and in 1867, the year the college welcomed its first class of 56 students, its President. During his presidency, he pressured the state government to increase funding for the new college and provide scholarships to enable poor students, including women, to attend. The college faced economic hardship early in its existence: enrollment dropped in the 1870s, and the college fell into debt. He is noted as well for helping to establish an agricultural college at Sapporo, Japan, and building strong ties between the Massachusetts Agricultural College and Hokkaido. After Clark was denied a leave of absence in 1879 to establish a “floating college” — a ship which would carry students and faculty around the world — he resigned.

The Clark Papers include materials from throughout his life, including correspondence with fellow professors and scientists, students in Japan, and family; materials relating to his Civil War service in the 21st Massachusetts Infantry; photographs and personal items; official correspondence and memoranda; published articles; books, articles, television, and radio materials relating to Clark, in Japanese and English; and materials regarding Hokkaido University and its continuing relationship with the University of Massachusetts.

W.E.B. Du Bois

Scholar, writer, editor of The Crisis and other journals, co-founder of the Niagara Movement, the NAACP, and the Pan African Congresses, international spokesperson for peace and for the rights of oppressed minorities, W.E.B. Du Bois was a son of Massachusetts who articulated the strivings of African Americans and developed a trenchant analysis of the problem of the color line in the twentieth century.

The Du Bois Papers contain almost 165 linear feet of the personal and professional papers of a remarkable social activist and intellectual. Touching on all aspects of his long life from his childhood during Reconstruction through the end of his life in 1963, the collection reflects the extraordinary breadth of his social and academic commitments from research in sociology to poetry and plays, from organizing for social change to organizing for Black consciousness.

Professor of English, adviser to student newspaper (The Collegian) and Jewish student organizations, University of Massachusetts, and founding member, College English Association.

The Goldberg Papers contain correspondence, speeches, published writings, papers written as a graduate student, biographical material, book reviews, subject files, newsclippings, and material from committees and projects with which he was involved, including the College English Association, College English Association Institute, Humanities Center for Liberal Education, and American Humanities Seminar.

William L. Machmer

Enjoying one of the longest tenures of any administrator in the history of the University of Massachusetts, William Lawson Machmer served under five presidents across 42 years, helping to guide the university through an economic depression, two world wars, and three name changes. During his years as Dean, Machmer witnessed the growth of the university from fewer than 500 students to almost 3,800, and helped guide its transformation from a small agricultural college into Massachusetts State College (1931) and finally into the University of Massachusetts (1947).

Machmer’s papers chronicle the fitful development of the University of Massachusetts from the days of Kenyon Butterfield’s innovations of the 1920s through the time of the GI Bill. The collection is particularly strong in documenting the academic experience of students and the changes affecting the various departments and programs at the University, with particular depth for the period during and after the Second World War.

Born in Germany in 1888, Henry Gustave Reinsch became an American citizen in 1912, serving in the military during the First World War, marrying an American girl, and starting a family. In 1942, however, two FBI agents showed up at Reinsch’s office, and a year later, Reinsch’s citizenship was revoked when he was accused by the U.S. government of living a double life — publicly loyal to America, privately loyal to Germany. Reinsch appealed the ruling to the Ninth Circuit Court and won. His citizenship was reinstated in 1945.

The Reinsch Papers contains newspaper clippings, personal and business correspondence, and official documents pertaining to both citizenship trials, that tell of uncommon wartime experiences.
