Jacob Isenschmid

Jacob Isenschmid, or Joseph Isenschmid (as mentioned in some sources), baptized by some newspapers of his time with the pseudonym "The Crazy Butcher", was a Swiss butcher who ended up being imprisoned for life in a British psychiatric hospital since September 1888. He was one of the contemporary suspects for the identity of the unidentified serial killer known as Jack the Ripper. Eventually, Scotland Yard ruled him out as a suspect, because, while he was imprisoned, other crimes attributed to the killer occurred.
