The collection richly documents Gansser’s experiences in the Michigan National Guard and veterans associations, as well as lists of Michigan soldiers killed in actions and troop rosters. The collection has a wide variety of photographs of encampments, officers, and units (group) photographs.
Michigan National Guard troops documented in this collection include: the 63rd Infantry; 125th Infantry; 32nd Division; 1st Battalion, 33rd Infantry, Company B; 119th and 120th Field Artillery, 32nd Division Band; and the 3rd Battalion, 125th Infantry. Camp MacArthur; Waco, Texas; the Division Headquarters for the 125th-128th infantries is also documented, as well as some general orders and circulars.
Gansser’s political career is documented in his Political Correspondence, 1905-1915, Correspondence and “Letters to the Editor,” 1911, and Correspondence from his Constituents, 1929. There is also Correspondence from Michigan Governor Fred M. Warner and Michigan Representative George A. Loud. A few drafts of his political Addresses (Speeches), 1911-1915, are also included in the collection.
Gansser’s activities in veterans groups, his non-political business interests, family correspondence, and two scrapbooks that belonged to his brother, Emil B. Gansser, complete the collection.
