He survived the toughest gangland days in Chicago and a stint in Alcatraz for tax evasion but notorious mob boss Al Capone couldn't escape the ravages of dementia and syphilis that left him prone to violent outbursts.
Medical records and letters documenting the final years of the tough gangster boss who didn't give a second thought to killing rivals, offer an insight into the sad demise of the infamous Chicago mobster as he descended into dementia and violent outbursts caused by syphilis.
In it, Moore suggests Capone's family hire a male nurse posing as a chauffeur to protect the public from the gangster's violent outbursts caused by his dementia.
'If, by any chance, Mr Capone makes an unprovoked attack upon a stranger, he is very likely to find himself in court for disturbing the peace and, as a result of that, to be recognized insane by the judge and to be committed to a Florida psychiatric hospital,' Moore wrote in 1941.
Moore said treatment had increased Capone's mental and intelligence quotient from that of a seven-year-old to that of a 14-year-old.
'However he is still silly, childish and mentally deteriorated,' Moore told Phillips.
Moore treated Capone for several years after he was released from prison in 1939, after serving nearly eight years for tax evasion and bootlegging.
Phillips cared for him for the remainder of his life. According to the medical charts and physicians' letters, Capone became 'recognizably insane' near the end of his stint in Alcatraz prison.
In a letter to Phillips in 1941, Capone asks about the doctor's family before requesting more 'of them red pills for bowels movement'.
