BOSTON (AP) — A former college professor who underwent a double arm transplant last month at Brigham and Women's Hospital in Boston said Tuesday that the best thing about the operation is that he's able to hug his loved ones again. Lautzenheiser is a former professor of film production and screenwriting at Boston University and Montana State University who became a quadruple amputee in 2011 following a life-threatening streptococcal infection.
