Felix "Milwaukee Phil" Alderisio was one of the Chicago Outfit's most feared hitmen. He is believed to have been boss from around 1969 to 1971. Originally from New York, he moved to Chicago when he was still a child. As a teenager, he moved to Milwaukee where he fought as a boxer under the name of "Milwaukee Phil". Unpopular as a leader, he was eventually convicted of bank fraud and extortion. While serving time for those convictions, he died at the federal prison in Marion in 1971 at the age of 59.
