Sebastian Wilhelm Valentin BauerBorn 23 Dec 1822; died 20 Jun 1875 at age 52.German inventor who was a pioneer of submarines. On 1 Feb 1851, in Kiel Harbour, he made a test-dive in his first submarine, Le Plongeur-Marin ("The Marine Diver"), only to sink 50-ft due to water leaks in the hull. He survived by waiting for the inside air pressure, compressed as more water leaked in, to match the water pressure outside. Seven hours later, he and his crew opened the hatch and rose to the surface to find funeral services in progress. In 1855, Bauer built a four-man treadmill-powered, 52-ft iron submarine, Le Diable-Marin ("The Marine Devil") carrying 11 crew. The photographs Bauer made through its windows are probably the first taken underwater. He also experimented on air purification and underwater sound signals.« |
