"Secret Self-Experimentation: How Their Discoveries Changed the Course of War"

During World War II, a group of scientists conducted extreme self-experiments to develop crucial diving research that helped the Allies win the war. Led by Professor John Burdon Sanderson Haldane and Dr. Helen Spurway, the scientists tested the effects of pressure and oxygen on their own bodies in hyperbaric chambers, leading to groundbreaking discoveries in underwater survival. Their work enabled Allied divers to safely scout and clear the waters off the coast of Normandy for the D-Day invasion, ultimately contributing to the success of the mission and the defeat of Hitler.
