"His whole family was really devoted to public service," his son said. Mr. MacNamara's father, James, "worked for the postal service. His sister is an Immaculate Heart nun, Sister Anne Bernadette."
The Defense Department moved Mr. MacNamara from Center City to offices in Moorestown and Camden, his son said, before he retired as a supervising contract administrator in 1993.
Since 1995, Mr. MacNamara had worked at a second career, as a part-time hall monitor at Washington Township High School.
The attraction of that work, his son said, was that "all my three brothers went to school there," and their mother, Marcella, is a special education aide there.
At the high school, a moment of silence was to take place in his honor Thursday.
Joseph Bollendorf, the high school principal, said Mr. MacNamara "was beloved by our staff and our students."
"He was helpful, he was friendly, he was engaging," he said.
Besides his wife, sister, and son, Mr. MacNamara is survived by sons Shawn, Kevin, and Brian, and two grandchildren.
A visitation was set for 4 to 4:45 p.m. Thursday, June 19, at Kain-Murphy Funeral Service, 15 West End Ave., Haddonfield, before a 5 p.m. memorial service. Interment will be private.
