This diving suit was designed and made by Joseph Peres in 1930 for use at extreme depths. It was in use until the mid-1930s when it was put in store. However, in 1969, the new offshore oil and gas industry once again required divers to go into very deep water and Jim 1 was resurrected to provide a prototype for a new generation of atmospheric suits. Rigid diving suits protect the diver from water presure, permitting breathing at normal atmospheric presure without having to undergo time-consuming decompresion.
