Thomas Vincent Monahan, 75, a Washington native and retired Winchester lawyer who had served as president of the Virginia Bar Association in 1975, died of cancer Nov. 13 at his home in Winchester, Va.

Mr. Monahan, who practiced civil law in Winchester from 1954 to 1998, was a past president of both the Virginia Trial Lawyers Association and the Winchester-Frederick County Bar Association. He also served as a state delegate to the American Bar Association, as vice president of the Virginia Association of Defense Attorneys, and as a fellow of the American College of Trial Lawyers.

He attended Princeton University before entering the Army in 1943. He later received an appointment to the U.S. Military Academy at West Point, from which he graduated in 1947. In 1951, he graduated at the head of his class at the University of Virginia law school, where he was a member of the Ravens Society and the Order of the Coif and was a law review editor.

In 1954, he retired from active military duty as an Air Force captain and began practicing law. In 1963, he helped form what became the Winchester law firm of Hall, Monahan, Engle, Mahan & Mitchell, from which he retired.
