John Deane (1800–1884; known as The Infernal Diver), with his brother Charles, invented the diving helmet and performed diving operations at the wreck of the Mary Rose. They received their education at The Royal Hospital School, Greenwich and were both in attendance in 1812. When he was 14, John joined the East India Company and sailed for seven years. In 1829, the Deane brothers sailed from Whitstable for trials of their new underwater apparatus, establishing the diving industry in the town. William Edwards was his partner between 1834 and 1855. Edwards died in the Crimean War (1854–1856).
