Philip Raidt, 65, a computer contractor and handyman who did a range of volunteer work in the Washington area, died Nov. 23 at the Washington Home hospice in the District.

He had mesothelioma, said his sister, Pam Raidt.

Mr. Raidt worked as an independent computer contractor in the 1970s and ’80s, specializing in network systems training and computer programming. He later was a handyman and retired several years ago after the diagnosis of his illness.

Mr. Raidt held leadership positions with the Greater Brookland Garden Club and did volunteer work with the Brookland Community Development Center, both in the District. He received a community service award from Washington’s Brookland neighborhood in 2005.

In the 1980s, Mr. Raidt worked with trail construction and maintenance crews on the Appalachian Trail. He also did volunteer math tutoring for local students over the years.

Philip Lloyd Raidt was born in St. Louis and settled in the Washington area in 1965. He was a District resident.

He participated in the anti-war movement in the 1960s and ’70s and remained active in environment causes throughout his life, his sister said. In the 1970s, he helped organize cultural activities and presentations on the campus of Catholic University, where he had been a student.

Survivors include his sister.
