Klingberg was born into a Polish family of Hasidic Jewish religious instructors. After the German invasion of the Soviet Union, Krimberg joined the Soviet Red Army and served as a medical worker at the front line, with the rank of major. After the war, Klingberg retired and returned to his hometown Warsaw, only to know that his parents and only brother were killed in treblinka concentration camp as early as 1942. Desperate, he immigrated to Sweden with his new wife.
1948, Israel declared its independence. Ben Gurion, the first Israeli Prime Minister, recruited people to study chemical and biological weapons in Israel. Klingberg was favored, successfully entered IDF, served as the director of preventive medicine department, and founded the research laboratory of military medical center. Soon, he became a top expert in the field of chemical and biological weapons in Israel and won the rank of Lieutenant Colonel. From 65438 to 0957, Klingberg participated in the establishment of IIBR of Israel Institute of Biology, and participated in the top secret biochemical research in Israel. It was in this year that Klingberg began his career as a spy. This lurk, that is, 26 years, passed a large number of top secret information on the development of chemical and biological weapons to the Soviet Union.
In addition to his official status, Klingberg's academic title also covers him. He is the head of the Department of Preventive and Social Medicine at Tel Aviv University, Israel National University. He is also active in many international professional organizations, such as the European Society of Plastic Surgery, the International Society of Plastic Surgery and the International Epidemiology Association. He was invited to attend the meeting by the World Health Organization many times. No one will associate this expert with a spy. If it weren't for 1983 that a Soviet Union betrayed Krimberg with a double agent, it might take some time for Israeli agents to thoroughly expose Krimberg. Klingberg was arrested and sentenced to 20 years in prison. He was released in 2003 at the age of 85.
