Paul Boyton (often misspelled Boynton) (b. June 29, 1848 in Ratthangan, Kildare county, Ireland — April 19, 1924), known as the Fearless Frogman, was a showman and adventurer some credit as having spurred worldwide interest in water sports as a hobby, particularly open-water swimming. Boyton, whose birthplace is variously listed as Dublin or Pittsburgh, Pennsylvania, is best known for his water stunts that captivated the world, including crossing the English Channel in a novel rubber suit that functioned similarly to a kayak.
