History gives no record of the date when diving first began or who the first divers may have been, but there are many records of man’s effort to breathe and operate underwater and of diving having taken place, mainly in naval warfare, as early as 400 B.C. It is recorded that the Alexander the Great descended in some form of diving bell, in 333 B.C. Most of this diving was carried out without special equipment. The equipment was consisted of a breathing tube to the diver’s mouth, the upper end of the tube being supported on the surface by a float. Not until the Middle Ages was any attempt made to supply air to a man underwater, and the history of modern diving is little over a century old, beginning with the appearance in 1837 of the ‘Closed’ Diving Dress and Helmet invented by Augustus Siebe. This was the greatest single advance ever made in the development of diving equipment, and this dress, essentially unchanged, is in world-wide use today and is known to us as the Standard Diving Dress.
