Biography
Born Joyel Barr in New York City to immigrant parents of Ukrainian-Jewish origin. He attended City College of New York with Julius Rosenberg and later worked with Rosenberg and Alfred Sarant at the United States Army Signal Corps laboratories at Fort Monmouth, New Jersey during World War II.
The Army Signal Corps Engineering Laboratories at Fort Monmouth, New Jersey, hired Barr as an electrical engineer in July 1940. Julius Rosenberg signed on with the corps as a junior engineer two months later. In 1941 they were recruited as Soviet spies by Jacob Golos. Barr's code name was Meter. They in turn persuaded Alfred Sarant to join the network.
According to Alexander Feklissov: "Joel and Alfred were good friends and spent a lot of time together. I must admit that Sarant had the makings of an undercover agent; he was a cautious young man, yet full of resolve, with progressive ideas. Before we recruited him though, he had to pass a test. Barr asked Sarant to borrow some secret documents to which he had access because he, Barr, needed them for his personal use. Alfred did not hesitate in helping his friend and in the meantime the Center approved a bona fide approach." However, he was at first reluctant to become a spy but was eventually convinced to join the network by Barr.
