After his university graduation, David Pincus joined the family business, a Philadelphia clothing manufacturing company named Pincus Bros.-Maxwell that had been established in 1911 by his father and uncles after their immigration to the U.S. from what is now
Belarus. Together with his older brother Nat, David Pincus expanded the company to become one of the city's largest manufacturers of men's clothing, employing as many as 1,100 people. For 35 years the business made
men's suits for
Bill Blass. In 2004, Pincus Bros.-Maxwell closed its factory due to foreign competition and declining demand for its products. ==References==
