Who, known as the Fearless Frogman, crossed the English Channel in 1875 in a rubber suit?

Paul Boyton was a world famous adventurer and showman, known as 'The Fearless Frogman'.

He specialised in daring stunts and challenges across water and set up the United States Life-Saving Service, a forerunner of today's Coastguards. He also developed a water sports park that became the forerunner of the Luna Park centres.
Some of his extravagant swimming feats included crossing the English Channel in 24 hours, travelling 430 miles along the River Rhine, and floating down the Mississippi River from Alton, Illinois to St Louis.
