Biographical note

Henry Larcom Abbot was born in Beverly, Massachusetts, in 1831. A descendant 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 Lieutenant R. S. Williamson, exploring routes in California and Oregon in 1855-1856. 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, he 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.

Publication note

Extracts from Henry Larcom Abbot's letters and journals were included in a two-part article by Robert W. Sawyer, "Abbot Railway Surveys," that was published in Oregon Historical Quarterly, Volume 33, No. 1 (March 1932) and Volume 33, No. 2 (June 1932). The article was reprinted the same year by the Oregon Historical Society Press under the title "Henry Larcom Abbot and the Pacific Railroad Surveys in Oregon, 1855."

The final Pacific Railroad Survey report was published by the War Department in 1857 as "Report of Lieut. Henry L. Abbot, Corps of Topographical Engineers upon explorations for a railroad route, from the Sacramento Valley to the Columbia River, made by Lieut. R.S. Williamson, Corps of Topographical Engineers, assisted by Lieut. Henry L. Abbot, Corps of Topographical Engineers."
