Christian J. Lambertsen
Christian James Lambertsen (May 15, 1917 – February 11, 2011) was an American environmental medicine and diving medicine specialist who was principally responsible for developing the United States Navy frogmen's rebreathers in the early 1940s for underwater warfare. Lambertsen designed a series of rebreathers in 1940 (patent filing date: 16 Dec 1940) and in 1944 (patent issue date: 2 May 1944)〔(Lambertsen's patent in ''Google Patents'' )〕 and first called his invention ''breathing apparatus''. Later, after the war, he called it ''Laru'' (portmanteau for Lambertsen Amphibious Respiratory Unit) and finally, in 1952, he changed his invention's name again to SCUBA (Self Contained Underwater Breathing Apparatus).〔(See Lambertsen's homage by the ''Passedaway.com'' website )〕 Although diving regulator technology was invented by Émile Gagnan and Jacques-Yves Cousteau in 1943 and wasn't originally related to rebreathers, the current use of the word SCUBA is largely attributed to Gagnan's and Cousteau's invention. The US Navy considers Lambertsen to be "the father of the Frogmen".

Lambertsen was born in Westfield, New Jersey and attended Rutgers University in New Brunswick, New Jersey, graduating in 1939 with a bachelor of science degree.〔Hevesi, Dennis. ("Christian Lambertsen, Inventor of Scuba Precursor, Dies at 93" ), ''The New York Times'', February 25, 2011. Accessed March 5, 2011. "Christian James Lambertsen was born in Westfield, N.J., on May 17, 1917, one of four children of Chris and Ellen Lambertsen."〕 He graduated from medical school at University of Pennsylvania, Philadelphia, Pennsylvania in 1943.
