Paul Boyton (often misspelled Boynton; 1848–1924), 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. As the founder of Sea Lion Park in 1895, Boyton is also known as the originator of the first modern amusement park with a fenced-in enclosure and admission charged at the gate. Early life and education Boyton attended Saint Francis University, Loretto, Pennsylvania. Eager for adventure at a young age, he reportedly joined the Union Navy during the American Civil War when he was 15, and in his young adulthood served stints with Benito Juárez's Mexican Navy and the French Franc-tireurs during the Franco-Prussian War. He eventually returned to the United States and helped organize the United States Life-Saving Service, one of the precursors to the modern-day United States Coast Guard. He was later appointed captain of Atlantic City, New Jersey's lifesaving service. Expeditions While in Atlantic City, Boyton began toying with a rubber suit invented by C. S. Merriman as a life-saving device for steamship passengers. This first immersion suit, which would become Boyton's trademark, was essentially a pair of rubber pants and shirt cinched tight at the waist. Within the suit were air pockets the wearer could inflate at will using tubes. Similar to modern-day drysuits, the suit also kept its wearer dry. This essentially allowed the wearer to float on his back, using a double-sided paddle to propel himself, feet-forward. Boyton made numerous expeditions in this suit, swimming up and down rivers across America and Europe to publicize its uses. Boyton would tow a small boat behind him in which he carried his supplies and personal possessions, and sometimes invited newspaper reporters to accompany him. A canny publicist, Boyton's arrival in small river towns was often heralded by great fanfare. Among his exploits were: crossed English channel in 24 hours (1875); paddled Rhine 430 miles (1875); Alton, Ill. to St. Louis, Mo. on the Mississippi (1876) and same year Bayou Goula to New Orleans, 100 miles in 24 hours; 400 miles on the Danube in six days (1876); navigated all important rivers of the continent, passed through
