Jack Kerouac
On October 20, 1969, around 11 in the morning, Kerouac was sitting in his favorite chair, drinking whiskey and malt liquor, trying to scribble notes for a book about his father's print shop in Lowell, Mass. He suddenly felt sick to his stomach, which was nothing unusual, and headed for the bathroom. He began to throw up large amounts of blood, and yelled to his wife, "Stella, I'm bleeding." Eventually he was persuaded to go to the hospital and was taken by ambulance to St. Anthony's in St. Petersburg. Blood continued to pour from his mouth and he underwent several transfusions. That evening he underwent surgery in an attempt to tie off all the burst blood vessels, but his damaged liver prevented his blood from clotting. Kerouac died at 5:15 the following morning, October 21, 1969, never having regained consciousness after the operation.
Grave site, Lowell, Massachusetts
His death, at the age of 47, was determined to be due to an internal hemorrhage (bleeding esophageal varices) caused by cirrhosis, the result of a lifetime of heavy drinking, along with complications from an untreated hernia and a bar fight he had been involved in weeks prior to his death.
