Henry Sullivan (swimmer)

Henry Sullivan (born c. 1893) was an American marathon swimmer who is best known for becoming the third person and the first American to swim across the English Channel, beginning his swim on the afternoon of August 5, 1923, from Dover, England and finishing 27 hours and 25 minutes later on the evening of August 6 at Calais, France.

The son of a businessman from Lowell, Massachusetts, Sullivan had been swimming since he was eight years old. He first attempted to make the crossing in 1913, two years after Thomas William Burgess became the second person to successfully complete the swim, but was forced to abandon the attempt a mere five miles from the French side of the Channel. In 1916, Sullivan outswam Charles Toth (a competitive swimmer who would also successfully swim the distance in 1923), setting an American record of continuously swimming for 20 hours and 28 minutes while attempting to swim from Provincetown, Massachusetts to Nantucket. He made two more attempts at the channel crossing in 1920, his best effort leaving him 1.5 miles from the French coast before unfavorable tides forced him to give up. In a 1921 attempt, he was forced to quit while within five miles of France after swimming for 19 hours and 5 minutes. Sullivan had sought to make an attempt at the crossing during the 1922 swimming season, but poor weather conditions led him not to make another try.

Sullivan was successful in his seventh attempt, in a calm sea and a water temperature of 62 degrees. He entered the water in Dover at 4:20 on Sunday afternoon, August 5, and began his swim. Though the straight-line distance is 22.5 miles, choppy waters and capricious tides forced him to swim an estimated 56 miles. He reached shore at Calais at 8:05 in the evening, was examined by a doctor and had something to eat. He was escorted out to the cheering crowd by Enrique Tirabocchi, an Argentine swimmer who would make the crossing himself later that year.
