In the final years of World War II, Austrian physician Wilhelm Beiglböck, serving as a Luftwaffe doctor, carried out brutal seawater experiments at the Dachau concentration camp.
Forty Roma and Sinti prisoners were forced to drink chemically treated seawater to test survival methods for downed German pilots. Victims suffered agonizing thirst, convulsions, and organ failure, with several dying in torment.
After the war, Beiglböck was convicted of war crimes and crimes against humanity, yet served only a few years in prison. He later returned to medical practice, his wealth inherited by Stille Hilfe (Silent Help) — a postwar network that aided former SS members. His story remains one of the most chilling examples of how Nazi doctors turned medicine into cruelty.
