EASTMAN, Seth, soldier, born in Brunswick, Maine, 24 January 1808; died in Washington, D. C., 31 August 1875. He was graduated at the U. S. military academy in 1829 and assigned to the infantry. After frontier and topographical duty he was assistant teacher of drawing at West Point from 1833 to 1840, served in the Florida war in 1840'1 and afterward on the western frontier. From 1850 to 1855 he was employed in the bureau of the commissioner of Indian affairs to illustrate the national work on the '" History, Condition, and Future Prospects of the Indian Tribes of the United States" (Washington, 1850'7). He then returned to the frontier. He was retired with the rank of lieutenant colonel on 3 December 1863, on account of disability from exposure in the line of duty, and on 9 August 1866, was brevetted brigadier general. General Eastman was elected a member of the National academy of design in 1838. He was the author of a "Treatise on Topographical Drawing" (1837).

His wife, Mary Henderson Eastman, author, born in Warrenton, Fauquier co. Virginia, in 1818, married Captain Eastman in 1835, and resided with him for many years at Fort Snelling, Minnesota, and at other frontier stations. Her portrayal of Indian life is the fruit of long observation and familiarity with the Indian character. She has published "Dacotah, or Life and Legends of the Sioux" (New York, 1849); "Romance of Indian Life" (Philadelphia, 1852); "Aunt Phillis's Cabin," a reply to Mrs. Stowe's "Uncle Tom's Cabin" (1852); "American Aboriginal Portfolio." illustrated by her husband (1853); "Chicora and other Regions of the Conquerors and the Conquered" (1854); "Tales of Fashionable Life" (1856); and numerous stories and sketches in magazines.

Their son, Robert Langdon Eastman, born in Maryland about 1840; died in Washington, D. C., 9 November 1865. He was graduated at the U. S. military academy in May 1861, and, being ordered at once to the seat of war, was engaged in the battle of Bull Run. From that time he was on duty with the Army of the Potomac, rising to the grade of captain, till he was prostrated by disease contracted in the service. After the battle of Malvern Hill he was ordered to West Point, and, though suffering from illness, performed the duty of assistant professor of drawing and of ethics until it was impossible for him to continue.
