He met his wife, Louise, in Boston while he was at MIT, and they married in 1968.They raised their family for 53 years in the Arlington home that he restored.

“Ed’s passion for the built world and his lifelong work ethic were instrumental in the firm’s early and continued success in hospitals and research laboratories, as well as universities and pharmaceutical and commercial buildings.

“Ed designed one of the first proton treatment centers in the country at the MGH Hospital and continued to design many more throughout the U.S. The office received numerous design awards and grew to 130 people. Ed blended humanism and technology in his award-winning work and remained a mentor to many.

“Ed taught at the Boston Architectural Center from 1970-1973, at the Harvard Graduate School of Design from 1974-1977, and was a critic/guest lecturer in urban design from 1978-1991. He was a respected president of the Boston Society of Architects 1994-1995 and received their Award of Honor in 2013. He was also a member of the AIA National Boards.”
