Dr. Joe Greenberg was born August 30, 1922 in Toronto. He attended Lansdowne Public School, was briefly enrolled at Central Tech and completed grade 9 at Central Commerce. In his youth, he was actively involved in the Jewish Boys' Club and attended B'nai Brith Camp. He enlisted in the Royal Canadian Air Force during the Second World War where he earned the ranking of Sergeant Major and was posted to an anti-aircraft squadron. Following the war, Joe had the opportunity to complete his high school matriculation and was accepted into Medical School at the University of Toronto. Upon graduation, he served his internship at St. Joseph's Hospital in Hamilton. He set up a general medical practice first on Grey St. and later on Bathurst St. He married Pebi (nee Rosenstein) in 1958 and they had 4 children. Joe was a very active member of the Russisher Shul (Shaare Tzedek) on Markham and Ulster St. Joe spent his formative years growing up on Major St. With the help of a local historian, Gus Sinclair, Joe was instrumental in the naming of a small lane branching off Major St. "The Boys of Major Street" in memory of the residents who served during the Second World War but did not return. Another lane was named "Greenberg Lane" in Joe's honour.
