Biography
Rapoport, a knitgoods-department organizer for the Needle Trades Workers Industrial Union, was briefly arrested with Markowitz at Vanity Knitting Mills, 140 West21st Street, New York, then freed under demonstrator pressure. The source supplies no first name. Similar trade and surname to Joseph Rappaport in 1936 are insufficient to establish identity; kept qualified pending further evidence.
