Haldane's oxygen apparatus for four people, London, England,
1901-1930 Haldane’s oxygen apparatus for four people allowed
four patients to receive oxygen at a pre-selected concentration
at any one time. British physiologist John Scott Haldane
(1860-1936) was famous for bold self-experimentation. This led
to important discoveries about the human body and the nature of
gases. He locked himself in sealed chambers breathing lethal
cocktails of gases while recording their effect on his mind and
body. He visited the scenes of mining disasters and investigated
their causes. The Germans first used poison gas in the First
World War. Haldane went to the Front at the request of British
Secretary of State Lord Kitchener. He attempted to identify the
gases being used. One outcome was his invention of the gas mask.
This apparatus was manufactured by George Salter and Company for
