The papers of Lewis Cass—advocate of U.S. expansion into Indian country, Governor of Michigan Territory from 1813 to 1831, U.S. Senator, Secretary of War and Secretary of State—came to the Clements Library in 1950. The papers had thought for 80 years to have been lost. Once a gift to the university from Lewis Cass Ledyard III (great-great grandson of Gen. Cass), the documents were used by Frank B. Woodford when writing his biography of Cass. The papers were found in a barn on Ledyard’s Long Island estate.
