Thomas Lincoln Casey was born in 1831 in New York and was the son of Lt. Col. Silas Casey. He graduated first in his class at the USMA at West Point in 1852 and became part of the Army’s elite Topographical Engineer Corps. He taught at the USMA between the years 1853–59.

For a brief time, First Lieutenant Casey commanded two detachments of sappers, or Engineers, at Ft. Steilacoom in 1860-61. While at the fort, 1860 Census records indicate that his family, consisting of his wife, Emma Weir, and two sons lived on post, in close proximity to his parents.

During the Civil War, Casey designed and built coastal fortifications in Maine. After the war, Casey was prolific in his building of public buildings and monuments in Washington City, particularly that of the Old Executive Office Building, Library of Congress, and completion of the unfinished Washington Monument.

He achieved the rank of Brigadier General and Chief of Engineers in the U.S. Army, being among its most famous and influential officers. He would later retire to the historic Casey Farm in Rhode Island, a site interpreted today as a classic example of New England architecture and agriculture.
