“In 1729, James Anderson was a prisoner in London’s Newgate Prison. While on the prison roof he accidentally fell over the side and onto a cart, which amputated both of his legs at the knees. When he woke up in the infirmary, he asked the doctor when they were going to install his new legs, meaning prosthetics. The doctor was confused, and had to explain to Anderson that prosthetics hadn’t been invented yet.”
