Summary

Operation Paperclip was a clandestine United States intelligence program initiated after World War II, between 1945 and 1959, to recruit over 1,600 German scientists, engineers, and technicians from former Nazi Germany. The operation, initially named Operation Overcast and later renamed Operation Paperclip, was conducted by the Joint Intelligence Objectives Agency (JIOA) and largely executed by special agents of the U.S. Army's Counterintelligence Corps (CIC). Many of the recruited individuals had been members of the Nazi Party, including the SS or SA. The primary objectives were to leverage German expertise for U.S. military research, particularly in fields like rocketry, aviation, and chemical/biological warfare, and to prevent this knowledge from falling into the hands of the Soviet Union amidst emerging Cold War tensions. Notable recruits included Wernher von Braun, a leading rocket scientist, and their contributions were instrumental in the development of the U.S. space program, including NASA and the Apollo missions, as well as military technology during the Cold War. The operation has been controversial due to the Nazi affiliations of many recruits and the ethical implications of integrating individuals associated with war crimes into American society. In response, the Soviet Union conducted a similar program, Operation Osoaviakhim, to acquire German scientific talent. The program is sometimes referenced in modern discussions, such as by David Friedberg on the All-In Podcast, as a strategic model for high-skilled talent recruitment.

Operation Paperclip

Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from former Nazi Germany to the US for government employment after the end of World War II in Europe, between 1945 and 1959; several were confirmed to be former members of the Nazi Party, including the SS or the SA. The effort began in earnest in 1945, as the Allies advanced into Germany and discovered a wealth of scientific talent and advanced research that had contributed to Germany's wartime technological advancements. The US Joint Chiefs of Staff officially established Operation Overcast (operations "Overcast" and "Paperclip" were related, and the terms are often used interchangeably) on July 20, 1945, with the dual aims of leveraging German expertise for the ongoing war effort against Japan and to bolster US postwar military research. The operation, conducted by the Joint Intelligence Objectives Agency (JIOA), was largely actioned by special agents of the US Army's Counterintelligence Corps (CIC). Many selected scientists were involved in the Nazi rocket program, aviation, or chemical/biological warfare. The Soviet Union in the following year conducted a similar program, called Operation Osoaviakhim, that emphasized many of the same fields of research. The operation, characterized by the recruitment of German specialists and their families, relocated more than 1600 experts to the US. It has been valued at US$10 billion in patents and industrial processes. Recruits included such notable figures as Wernher von Braun, a leading rocket-technology scientist. Those recruited were instrumental in the development of the US space program and military technology during the Cold War. Despite its contributions to American scientific advances, Operation Paperclip has been controversial because of the Nazi affiliations of many recruits, and the ethics of assimilating individuals associated with war crimes into American society. The operation was not solely focused on rocketry; efforts were directed toward synthetic fuels, medicine, and other fields of research. Notable advances in aeronautics fostered rocket and space-flight technologies pivotal in the Space Race. The operation played a crucial role in the establishment of NASA and the success of the Apollo missions to the Moon. Operation Paperclip was part of a broader strategy by the US to harness German scientific talent in the face of emerging Cold War tensions, and ensuring this expertise did not fall into the hands of the Soviet Union or other nations. The operation's legacy has remained controversial in subsequent decades.

  • Project Paperclip and American Rocketry after World War II

    Project Paperclip was the second name for a program to bring German and Austrian engineers, scientists, and technicians to the United States after the end of World War II in Europe. Known by many today as “Operation Paperclip,” which is actually a misnomer, it was originally called Project Overcast. Its official objective was to bring these experts to the United States for six months to a year to help America in the war against Japan. But that war suddenly ended in August 1945 and the program

  • How Operation Paperclip brought Nazi scientists to the U.S.

    Operation Paperclip—sometimes called Project Paperclip—was overseen by the Joint Intelligence Objectives Agency. It hoped to harness this technological expertise to develop America’s aeronautics, military, and space programs. Lasting officially until 1947, but continuing on through similar programs until 1962, Operation Paperclip brought 1,500 scientists from Germany and Austria to the United States, where most of them became citizens. [...] HISTORY & CULTURE # How Operation Paperclip brought Nazi scientists to the U.S. After World War II, Operation Paperclip quietly recruited German scientists to work on its most advanced weapons and space programs—including some who had been active in the Third Reich. The first U.S. test of a captured German V2 in 1946. At the end of World War II, a race began between the United States and the USSR to retrieve as many V2 rockets and staff as possible. [...] The program’s name boils down to the use of paperclips as a kind of earmark on candidates’ files. According to journalist Eric Lichtblau’s book The Nazis Next Door: HowAmerica Became a Safe Haven for Hitler's Men, recruiters vetted scientists to learn whether they were current members of the Nazi Party or sympathetic to the party’s core tenants—officially, at least. And so, officials “placed paperclips at the top of security dossiers for the scientists that interested them,” Crim explains.

  • Families of Operation Paperclip

    In 1945 during the cold war and the space race with Russia, the United States conducted Operation Paperclip. Over 1600 German scientists, engineers, and technicians were taken from Germany to work for the U.S. government. Operation Paperclip’s purpose was to aid and advance the U.S. military during the cold war. This isn’t a video about the scientists and engineers, but about the 108 families stationed at Fort Bliss in El Paso, Texas. Thank you for watching From the Space Vault!

Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from the former Nazi Germany to the U.S. for government employment after the end of World War II in Europe, between 1945 and 1959. Conducted by the Joint Intelligence Objectives Agency (JIOA), it was largely carried out by special agents of the U.S. Army's Counterintelligence Corps (CIC). Many of these personnel were former members and some were former leaders of the Nazi Party. In February 1945, Supreme Headquarters Allied Expeditionary Force (SHAEF) set up T-Force, or Special Sections Subdivision, which grew to over 2,000 personnel by June. T-Force examined 5,000 German targets with a high priority on synthetic rubber and oil catalysts, new designs in armored equipment, V-2 (rocket) weapons, jet and rocket propelled aircraft, naval equipment, field radios, secret writing chemicals, aero medicine research, gliders, and "scientific and industrial personalities”. When large numbers of German scientists began to be discovered in late April, Special Sections Subdivision set up the Enemy Personnel Exploitation Section to manage and interrogate them. The Enemy Personnel Exploitation Section established a detention center, DUSTBIN, first in Paris and later in Kransberg Castle outside Frankfurt. The US Joint Chiefs of Staff (JCS) established the first secret recruitment program, called Operation Overcast, on July 20, 1945, initially "to assist in shortening the Japanese war and to aid our postwar military research". The term "Overcast" was the name first given by the German scientists' family members for the housing camp where they were held in Bavaria. In late summer 1945, the JCS established the JIOA, a subcommittee of the Joint Intelligence Community, to directly oversee Operation Overcast and later Operation Paperclip. The JIOA representatives included the army's director of intelligence, the chief of naval intelligence, the assistant chief of Air Staff-2 (air force intelligence), and a representative from the State Department. In November 1945, Operation Overcast was renamed Operation Paperclip by Ordnance Corps officers, who would attach a paperclip to the folders of those rocket experts whom they wished to employ in the United States. The primary purpose for Operation Paperclip was U.S. military advantage in the Soviet–American Cold War and the Space Race. The Soviet Union responded by relocating more than 2,200 German specialists—a total of more than 6,000 people including family members—with Operation Osoaviakhim during one night on October 22, 1946. In a secret directive circulated on September 3, 1946, President Truman officially approved Operation Paperclip and expanded it to include 1,000 German scientists under "temporary, limited military custody".
