Michigan State Police Commissioner, National Guard Commander and businessman; correspondence, clippings, diary, photographs, and other materials relating to his career.
The collection consists of a scattering of correspondence, photographs, and biographical material. Much of the collection is clippings and ephemera. There is, however, a diary for 1920 which includes Vandercook's notes on "red" raids of the 1920's and comment on Governor Alexander J. Groesbeck. Also of interest are some payrolls for Battery A of the First Field Artillery, also an Order Book.
