Trivia

Owen Churchill, already a wealthy man, became a multi-millionaire from his "invention" of the first popular swim fin, which gained in use in the late 1930s and early 1940s. The income from his then-patented and now-commonplace device let him pursue his passion of competitive sailing. Churchill became the primary patron and team captain of the United States Olympic Yachting team at both the 1932 (Los Angeles) and 1936 (Berlin) Olympic Games. Churchill was also a lifetime member of the Los Angeles Yacht Club, where memorabilia of his exploits is on display to this day. During the 1984 Olympic Games in Los Angeles, special recognition was given to Churchill by Peter Ueberroth for his lifelong efforts to promote sailing. Churchill's Star Fleet yacht, The Angelita, was fully restored for the occasion and re-christened at the time in Los Angeles harbor.
