The creation and use of the earliest functional diving helmet is credited to the Italian physicist, ‘Guglielmo de Lorena’. He experimented with an early form of diving helmet (either in 1531 or 1535, dates vary) while trying to locate two ancient roman ships in Lake Nemi, near Rome. These ships were rumoured to be carrying a cargo of gold. Guglielmo de Lorena constructed a barrel shaped bell which was put over the divers head and allowed him to walk underwater for almost an hour.
