After graduating from Harvard, Roosevelt worked for the
DuPont company from 1936 to 1941.
Service in World War II Following the Roosevelt tradition of military service during times of national emergency, during World War II, Roosevelt volunteered as a Navy pilot, serving as a flag lieutenant (i.e. an aide to an admiral) in the Pacific theater. For his service as a naval aviator, Theodore was awarded the
Air Medal. He was promoted to lieutenant on April 1, 1944, and left the Navy as a lieutenant commander.
Post-war life Upon his return from the Pacific Theater, Theodore joined the Philadelphia brokerage firm of Montgomery, Scott, becoming a partner in 1952. For many years, he was president of the Competitive Enterprise System, Inc., a nonprofit organization that promoted free markets in the United States. Roosevelt was a trustee of the
Theodore Roosevelt Association (TRA) for many years and a generous supporter of the organization. In recent years, he attended TRA Police Awards ceremonies in Boston and Philadelphia as well as TRA annual meetings in Boston and Norfolk, VA. He was an honorary plank owner in the
USS Theodore Roosevelt, and a strong supporter of the efforts to preserve the
Pine Knot site in Virginia, his grandparents' presidential retreat. ==Personal life==
