The Roman Catholic priest from Long Island nationally known as half of the God Squad, a popular television show about religion, died following a years-long battle with Parkinson’s disease. He was 69. Father Tom, as he was known, became a household name with Rabbi Marc Gellman following the success of the TV show they co-hosted for 20 years on Telecare, the faith-based cable network that Hartman ran for the Diocese of Rockville Centre. The show led to a nationally-syndicated newspaper column, as well as regular TV and radio appearances on shows with larger audiences than their own, such as 'Good Morning America.' After his diagnosis, Hartman stepped back from the spotlight and founded a charity that donated millions to find a cure for Parkinson’s.
