Thomas Dudley Cabot (May 1, 1897 - June 8, 1995) was born in Cambridge, Massachusetts, the son of Godfrey Lowell Cabot and Maria Buckminster (Moors) Cabot. He was a prominent American business executive who became a consultant to the U.S. State Department.
He graduated from Harvard University, and then married Virginia Wellington on May 15, 1920, and together they had five children: Louis Wellington, Thomas Dudley, Robert Moors, Linda (Mrs. L. C. Black), Edmund Billings. He was the brother of John Moors Cabot and Elise (Cabot) Forbes.
He served as the CEO of the Cabot Corporation from 1922 to 1960 (the company was founded by his father); and was named the first director of the Office of International Security Affairs in 1950, where he worked as a consultant to the U. S. Department of State.
In May of 1960, a company called The Gibraltar Steamship Corporation announced that it had leased land on Swan Island off the coast of Nicaragua to operate a radio station for broadcast in Cuba and the Caribbean. Cabot was named as president of the newly-formed company, Radio Swan, which claimed to represent Cuban exiles, but was actually a covert project controlled by the CIA to win supporters for U.S. policies and discredit Castro.
