I shared his family in census records here (1895-1915) and here (1920-1940).
I'm not sure where he attended medical school, but by June 1917, according to his WWI Draft Card, he was working as a Physician at Beth Israel Hospital in Newark, N.J.

The Brooklyn Daily Eagle can be found online at Brooklyn Newsstand. (Any issues not found there might be found at Fulton History.) I found several articles that mentioned Dr. Matthew S. Levitas in the 1940s and early 1950s. A select few follow.
During World War II, Dr. Levitas served as chairman of the V.F.W.'s Civilian Defense Medical Unit. After the war, he continued to work on behalf of the Veterans of Foreign Wars as national surgeon-general of the V.F.W., encouraging the establishment of a national blood bank and encouraging blood donation, starting in 1947:

Matthew S. Levitas never married. He died on February 20, 1956, and is buried at Long Island National Cemetery in Farmingdale, N.Y. He is memorialized at Find A Grave.
