During a book signing event in Harlem in 1958, the first assassination attempt on Dr. Martin Luther King's life came at the hands of Izola Ware Curry, who was later diagnosed as a paranoid schizophrenic. King almost died that day at Blumstein’s department store. When two responding police officers arrived, they found King sitting in a chair with an ivory-handled letter opener stuck in his chest.
The police carried the chair and King to a waiting ambulance, telling him, "Don't sneeze; don't even speak." The surgeon at New York's Harlem Hospital embarked upon a delicate, time-consuming rescue operation -- the sharp tip of the letter opener was touching King's aorta, and his chest had to be opened up to get it out. "If you had sneezed during all those hours of waiting," Dr. Aubrey Maynard later told King, "your aorta would have been punctured and you would have drowned in your own blood."
