Governor of Michigan, writer, businessman; papers include correspondence, business records, speeches, writings, visual materials, diaries.

The Osborn collection consists of correspondence, diaries, business papers, scrapbooks, photographs, and other materials accumulated during his life. Materials prior to 1889 are scarce possibly because of a fire which destroyed Osborn's home; thereafter and up to the time of his death in 1949, the Osborn papers are voluminous, documenting each of this man's varied activities. Although his career as elected public official was limited to one term as governor, the collection reflects the importance of his life in areas beyond politics alone. His voice was heard, in letters and speeches and monographs, speaking out on the issues of the day - prohibition, conservation, the New Deal, and of course his life-long interest in the development of Michigan's Upper Peninsula economy and natural resources.
