Julius Rosenberg joined the
Army Signal Corps Engineering Laboratories at
Fort Monmouth, New Jersey, in 1940, where he worked as an engineer-inspector until 1945. He was discharged when the
U.S. Army discovered his previous membership in the
Communist Party USA. Important research on electronics, communications,
radar and
guided missile controls was undertaken at Fort Monmouth during
World War II.

According to a 2001 book by his former
handler Aleksandr Feklisov, Rosenberg was originally recruited to spy for the interior ministry of the Soviet Union,
NKVD, on
Labor Day 1942 by a former
spymaster Semyon Semyonov.
[13] Rosenberg had been introduced to Semyonov by Bernard Schuster, a high-ranking member of the Communist Party USA and NKVD liaison for
Earl Browder. After Semyonov was recalled to Moscow in 1944 his duties were taken over by Feklisov.
[13]
Rosenberg provided thousands of classified reports from
Emerson Radio, including a complete
proximity fuze. Under Feklisov's supervision, Rosenberg recruited sympathetic individuals into NKVD service, including
Joel Barr,
Alfred Sarant,
William Perl, and
Morton Sobell, also an engineer.
[14] Perl supplied Feklisov, under Rosenberg's direction, with thousands of documents from the
National Advisory Committee for Aeronautics, including a complete set of design and production drawings for
Lockheed's P-80 Shooting Star, the first U.S. operational
jet fighter. Feklisov learned through Rosenberg that Ethel's brother David was working on the
top-secret Manhattan Project at the
Los Alamos National Laboratory; he directed Julius to recruit David.
[13]
In February 1944, Rosenberg succeeded in recruiting a second source of Manhattan Project information, engineer
Russell McNutt, who worked on designs for the plants at
Oak Ridge National Laboratory. For this success Rosenberg received a $100 bonus. McNutt's employment provided access to secrets about processes for manufacturing
weapons-grade uranium."
