Historical NoteReturn to Top

Henry Larcom Abbot was born in Beverly, Massachusetts, in 1831. The descendent of Revolutionary War veterans, he graduated from West Point in 1854, joining the Army Topographical Engineers soon after. He was part of the Pacific Railroad Survey led by Lieut. R.S. Williamson, exploring routes in California and Oregon in 1855-56. He next investigated flood control and channel improvement on the Mississippi River. During the Civil War he was wounded at Bull Run, and eventually received seven brevets, ending as major-general of volunteers. After the war Abbot was placed in charge of the engineer battalion and established the Army's Engineer School of Application in New York. He became an authority on high explosives and, following his retirement from the Army in 1895, became involved in the building of the Panama Canal. He was a member of the engineer board, and actively championed a lock canal over the sea level design favored by others. He died in Cambridge, Massachusetts, in 1927 at age 96.
