The ‘Jim Suit’ was largely inspired by the German ‘Panzertaucher’ Atmospheric Diving Suit ( ADS ) as built by ‘Neufeldt und Kuhnke’ in the first halve of the 20th century ( see the Neufeldt und Kuhnke chapter on this website ) The first ‘Jim Suit’ was built in 1969 by Mike Humphrey and Mike Borrow, partners in the English firm Underwater Marine Equipment Limited (UMEL), who were assisted by Joseph Salim Peress. Peress had built his first atmospheric diving suit in 1924, he also had the Neufeldt und Kuhnke ‘Panzertaucher’ as his main inspiration. The ‘Jim Suit’ was named after Jim Jarrett who had been Peress' chief diver.
