A service has been held for Dr. Lang, who in addition to his wife and son leaves two daughters, Kiran Milunsky of Newton and Brittany Smith of Brunswick, Maine; two brothers, Vaughn and Martin; and three grandchildren.
Proud of his faith, Dr. Lang started seriously studying Judaism as he got older, eventually joining a weekly Torah study group.
“His enthusiasm and passion was felt by everyone in the group,” said Rabbi Yisroel Freeman of the Chabad Jewish Center of Sudbury. “He really connected with his heritage and spirituality. He was an inspiring person to me. Even during his difficult moments, his drive for learning continued.”
Dr. Lang’s visit to Israel in 2010 was his last trip before being diagnosed with cancer in early 2011.
“He could have been a very sick man who did nothing in those 2½ years,” his wife said, “but he chose to keep living, moving, doing.”
