The case of Dr Pownall - mad doctor, sane patient and insane murderer.

Dr Pownall was a surgeon, asylum proprietor and one-time mayor of Calne who had bouts of insanity. He had two serious bouts of violence when insane, and later murdered a servant, Louisa Cook, after his discharge from Northwoods Asylum as recovered. He was tried for murder and ended up in Broadmoor, where he died in 1882. There are extensive contemporary public accounts of the case, but detailed examination of the roles of the local chief magistrate, Purnell Barnsby Purnell, and Pownall's brother-in-law and asylum doctor, Dr Ogilvie, reveals severe tensions that adversely influenced events. Everyone defended themselves, and few lessons were learned about cooperation.
