The Ancestry.com blog lists some, well interesting, causes of death from those days of yesteryear. Some examples:
Accidental deaths may be reported in newspapers, as was the case with Ohio politician and lawyer, Clement Vallandigham. Clement was defending a murder suspect and trying to demonstrate the possibility that the victim had shot himself. He attempted to demonstrate his theory, but grabbed a loaded gun by accident. His reenactment proved fatal. This article from The Herald and Torch Light of Hagerstown, Maryland (21 June 1871) describes the accident and the aftermath.
Then, there was the sad case of the beloved Jack Daniels (Yes, THAT Jack Daniels).
Although Jack Daniel’s death certificate only lists “blood poisoning from operation,” the full story of the famous distiller’s death is a bit unusual. Apparently in frustration in not being able to open his safe, he kicked it, injuring his toe. The resulting infection was responsible for his death. The deadly safe is on display in Jack Daniel’s distillery in Lynchburg.
Wait until you see the one from the Wild, Wild West. It reads like an account of the NRA's Gun Appreciation Day.
