Benjamin Alvord (1813-84) Signed Slip, "Benj. Alvord, Brig General, U. S. Volunteers", 5.25 X 1.75, was an American soldier, mathematician, and botanist. He was a West Point graduate and also a professor of mathematics at the military academy. He participated in the Seminole Wars (three related military conflicts in Florida) and subsequently, served during the Mexican-American War for which he was recognized for gallantry in a number of important battles including the Battle of Palo Alto and the Battle of Resaca de la Palma. From 1862 to 1865, during the American Civil War, Alvord was at Fort Vancouver as the commander of the District of Oregon with the rank of brigadier general of volunteers. He was named to that post because it had a history of friction between the native peoples and settlers. After the war he became Paymaster General of the Army. He also wrote several books on mathematics and natural history. This large, bold, ink signature and rank is in fine condition, with a tight trim at the top touching a couple of letters.
