Last week we introduced to you the totally awesome Exosuit, a $600,000 atmospheric diving suit, capable of taking a human 1,000 feet underwater at surface pressure. This means that the diver doesn't have to decompress and there is no need for special breathing gas mixtures, so there is no danger of decompression sickness or nitrogen narcosis.
Engineers have been trying to build hard, armoured suits since the 19th century; below is a brief history of these amazing deep-sea scaphanders.
This deep-sea atmospheric diving suit, designed by Alphonse and Théodore Carmagnolle (Marseille, France), was patented in 1882. It was the first properly anthropomorphic design. Sadly it never worked properly.

Iron Mike was built in 1930 by the New York Empire Marine Salvage Engineering Company to help in the recovery of sunken treasure and other valuable goods. It was designed by Thomas Patrick Connelly, patented only in 1935.

This piece of diving armor is referred to as Hagenuk or Iron Duke. It was made by Hagenuk in Kiel, Germany. In 1931 Iron Duke dove down to 450 feet to salvage sunken treasure from the wreck of the Egypt. The diver recovered 10 tons of silver and 5 tons of gold. It was the greatest treasure salvage of all time.

Tritonia, Joseph Salim Peress' 1-atm dive suit (on the left), explored the Lusitania wreck in 1935. Jim Jarrett was Peress's chief diver and made this dive to 312 feet. This suit was a precursor to the "Jim" suit, named for Jim Jarrett.

The JIM suit was invented in 1969 by Mike Humphrey and Mike Borrow*, partners in the English firm Underwater Marine Equipment Ltd (UMEL), assisted by Joseph Salim Peress. JIM is named after Jim Jarrett, Tritonia suit diver and Lusitania explorer.

The ADS 2000 was developed jointly with OceanWorks International Corp. and the US Navy in 1997, as an evolution of the Newtsuit to meet US Navy requirements. In 2006 Chief Navy Diver (DSW/SS) Daniel P. Jackson submerged 2,000 feet, setting a record using the ADS 2000.
