Alfred Sarant Alfred Epaminondas Sarant , also known as Filipp Georgievich Staros and Philip Georgievich Staros ( 1918 - March 12 , 1979 ) , was an engineer and a member of the Communist party in New York City in 1944 . He was part of the Rosenberg spy ring that reported to Soviet intelligence . Sarant worked on secret military radar at the United States Army Signal Corps laboratories at Fort Monmouth , New Jersey . Alexandre Feklisov , one of the KGB case officers who handled the Rosenberg spy apparatus described Sarant and Joel Barr as among the most productive members of the group . Sarant was recruited as a Soviet espionage agent by Barr . The Venona project transcript of 14 November 1944 reported to Moscow that Sarant had been successfully recruited . The transcript noted Sarant and Barr were roommates and good friends and proposed to pair them off and get them to photograph their own materials . Initially Barr delivered film to Rosenberg , who passed it on to officers of the Soviet intelligence . Later , Barr met directly with KGB officers ; Sarant did not have direct contact with the KGB in the U . S . One transcript reports Sarant and Barr delivered 17 authentic drawings relating to the APQ - 7 , an advanced and secret airborne radar system developed jointly by the Massachusetts Institute of Technology and Western Electric for the United States military . In 1946 Sarant moved to Ithaca , New York where he worked at Cornell University in the physics laboratories . Sarant ' s next door neighbor was Philip Morrison , a former Manhattan Project scientist and personal friend who joined the Communist Party of the United States in 1939 . Sarant knew several prominent physicists socially , including Hans Bethe and Richard Feynman . Two days after Julius Rosenberg ' s arrest on 17 July 1950 , the FBI interviewed Sarant but did not arrest him , although it possessed decrypted KGB cables that clearly identified Sarant as a member of the Rosenberg ring . Three days later Sarant ran away with Carol Dayton , the wife of his close friend and neighbor , Bruce Dayton ; Sarant and Dayton abandoned their children and spouses . The two crossed into Mexico and eluded the FBI . In Mexico City , Sarant sought assistance from officials at an obscure Polish trade office , guessing correctly that they were intelligence officers . Following instructions from the KGB , the Poles hid Sarant and Dayton in Mexico , then engineered an escape that crossing the border to Guatemala on foot , taking a freighter to Casa Blanca , and flying to Poland via Spain . After six months in Warsaw they moved on to Moscow . The KGB arranged a dramatic reunion with Barr , who was summoned from Prague , where he had fled shortly after the Rosenberg ring started to unravel . Sarant was assigned a new identity , Philip Georgievich Staros , claiming a Canadian background to explain his accent . From Moscow , Barr and Sarant were resettled in Czechoslovakia and put to work as electrical engineers . They led a team that designed and built a prototype of the Soviet bloc ' s first automated anti - aircraft weapon . Their technology was quickly deployed and was in use , with some minor modifications , into the 1980s . In 1956 Sarant and Barr moved to Leningrad where they were placed in charge of a military electronics research institute . They have been credited with being the founders of the Soviet microelectronics industry , in part because Sarant and Barr conceived of , designed and won political backing for the creation of Zelenograd , the Soviet Union ' s Silicon Valley . Sarant was the scientific director of Zelenograd until Nikita Khrushchev ' s forced retirement . In 1969 Sarant received a state honor for the UM - 1 , a computer that was widely used in Soviet industry . He led the team that created the Uzel , the first digital computer installed in a Soviet submarine . The Uzel was integrated into the Kilo class submarines and as of 2007 was still in use in the Russian , Iranian , Chinese and Indian navies . In 1979 Sarant died of a heart attack . Carol Dayton , the woman who fled with him , returned to the United States in 1991 . It was not until 1983 , thirty - three years after Sarant ' s flight to Mexico , that the full story of Sarant ' s life was told . A Russian émigré working at Harvard , Mark Kuchment , who had read " The Rosenberg File " linked Barr and Sarant to two prominent Soviet scientists , both native speakers of English . Sarant ' s cover name in Soviet intelligence and in the Venona project is " Hughes " . Alfred Sarant ' s two sons , Stephen Nonda Sarant ( Rutherfordton , NC ) and Jeremy Phillip Sarant ( Portland , Oregon ) and his two daughters , Tonya and Kristina Staros ( both of California ) are all still alive and open for interviews .
