Edmund Caunce Nowell 'Ted' Heaton (late 1872 – 19 September 1937) was a British diver and swimming instructor born in Liverpool, England. He is notable for his small tank diving displays during the late 19th century and for his several unsuccessful attempts to swim the English Channel during the early 20th century. Having begun training to swim the channel in 1893, he made a total of seven attempts. He often came within several miles of the French coast, with the closest being in August 1909 when he came within 2 miles (3.2 km). His swimming efforts earned him a role as a superintendent of his local swimming baths and a salary of £120 a year which also included accommodation and energy provision.
