Henry Clay Warmoth (1842–1931) was a plantation owner, Union Army officer, railroad builder, and Governor of Louisiana. Correspondence deals with personal diaries, plantation journals (Magnolia Plantation in Plaquemines Parish, La.), politics and personal activities. He was impeached and suspended from office during the final days of his term in 1872 due to political turmoil. This event led to the swearing-in of P.B.S. Pinchback, President of the State Senate, as the first black Governor in the United States. Warmoth’s papers (1798–1934) include correspondence, diaries, plantation records, and scrapbooks.
