Levitt learned his trade in the Navy during WWII building barracks.
Of course, about 20 miles south of me is the New Jersey Levittown, now called Willingboro. It is notable because it was built in response to criticisms about the Levitts refusing to sell to blacks at the time (Levittown/Willingboro, NJ continuing to be a stronghold of the black middle class to this day).
