In 1929, American engineer Otis Barton built the Bathysphere, the first deep-sea submarine – more like a spherical diver – and changed diving history.
The Bathysphere consisted of a hollow sphere of cast steel one inch (25 mm) thick, 1.45 meters in diameter.
Its weight was 2.25 tons above water, although its buoyancy reduced it by 1.4 tons when submerged.
The steel cable that supplied oxygen to the cabin and connected it to the vessel on the sea surface weighed an additional 1.35 tonnes.
From 1930 to 1934, Barton, along with naturalist William Beebe, dived off Bermuda to study underwater wildlife at depths never before reached by other divers.
In fact, the deep dive record of 923 meters on August 15, 1934, held until 1949, when Barton dived with another vessel called the Benthoscope.

Huddled inside the capsule and using a telephone system from Bell Laboratories, Beebe described live to the outside world the amazing marine life he was watching through his tiny quartz window.
