Bruno Spitzer was the son of Rabbi David Spitzer and the brother of Harry Spitzer. Bruno was the only member of the family to have escaped Czechoslovakia prior to the German invasion. While most of the Spitzer family perished in the Holocaust, Bruno (an active and well-known political lawyer in Czechoslovakia) and his wife, Draga, came to the United States in 1939. Upon arriving in Massachusetts, Bruno worked as a laborer in a furniture factory. They lived for 21 years in Lynn, moved to Austria for a brief time, and returned to the United States to settle in Brookline.
