The first anthropomorphic deep-sea diving suit appeared on the coast of Marseille. In 1878, two brothers, Alphonse and Theodore, showed the public the first version of the suit: a metal prototype weighing 380 kilograms with twenty-five two-inch portholes in a helmet and movable joints (six segments for the arm, four for the leg and two segments for the belt).
The design aroused interest and the brothers were granted patent number FR132761. However, the suit did not go to the series, as it was not waterproof.
Today, the invention of Theodore and Alphonse Carmagnolle is a part of an exhibit of the French National Maritime Museum in Paris, where it inspires visitors with its monumental forms and overall expressiveness.
That's a cool project Michael! 380 kilos.... wow ! 😮😮
