A bathysphere is a pressurized metal sphere that allows people to go deep in the ocean, to depths at which diving unaided is impossible. This hollow cast iron sphere with very thick walls is lowered and raised from a ship using a steel cable. The bathysphere was invented by William Beebe and Otis Barton (around 1930). William Beebe (1877 - 1962), an American naturalist and undersea explorer, tested the bathysphere in 1930, going down to 1426 feet in a 4'9" (1.45 m) diameter bathysphere. Beebe and Otis Barton descended about 3,000 ft (914 m) feet in a larger bathysphere in 1934. They descended off the coast of Nonsuch Island, Bermuda in the Atlantic Ocean. During the dive, they communicated with the surface via telephone.
