In 1935, a Portuguese doctor named Egas Moniz learned of an operation done on chimpanzees to reduce their violent nature. The operation involved removing part of their frontal lobe. Montaz experimented on unsuspecting victims developing the barbaric and heinous procedure known as a lobotomy. Between the years of 1945-1947, 2,000 lobotomies were performed. After Montaz was awarded the Nobel Prize for Medicine, that number rose to a staggering 18,000 unfortunate souls.
