Theodore Roosevelt IV (ˈroʊzəvɛlt ; June 14, 1914 – May 2, 2001), also known as Theodore III, was an American banker, government official, and veteran of World War II. He was a grandson of President Theodore Roosevelt through his father, Brig. Gen. Theodore Roosevelt III. His name suffix varies since President Roosevelt's father was Theodore Roosevelt Sr., though the same-named son did not commonly use a "Jr." name suffix. Roosevelt was born on June 14, 1914, in New York City. He was the second born and the last surviving of four children to Theodore Jr. and Eleanor Butler Alexander. Theodore had an older sister, Grace Green Roosevelt, who married William McMillan, and two younger brothers, Cornelius Van Schaack Roosevelt III and Quentin Roosevelt II. Following his father, Ted, and paternal grandfather, T. R., Theodore went to Groton School and graduated from Harvard in 1936, where he was a member of the Hasty Pudding Theatricals and the Owl Club. While at Harvard, Roosevelt played for the Harvard Crimson men's soccer team, and was named a second-team All American in 1934. When his grandfather, President Theodore "T. R." Roosevelt Jr., died in 1919, his father took on the "Junior" last name suffix. As a result, he was known as Theodore III, rather than Theodore IV. As an Oyster Bay Roosevelt, Ted was a descendant of the Schuyler family. His maternal grandparents are Henry Addison Alexander and Grace Green. After graduating from Harvard, Roosevelt worked for the DuPont company from 1936 to 1941. 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. Upon his return from the Pacific Theater, Theodore joined the Philadelphia brokerage firm of Montgomery, Scott, becoming a partner in 1952.
