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 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, was largely actioned by special agents of the US Army's Counterintelligence Corps. 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 1500 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.
Background and Operation Overcast
In February 1945, Supreme Headquarters Allied Expeditionary Force set up T-Force, or Special Sections Subdivision, which grew to over 2,000 personnel by June. T-Force examined 5,000 German targets, seeking expertise in synthetic rubber and oil catalysts, new designs in armored equipment, V-2 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 by the advancing Allied forces in late April 1945, the Special Sections Subdivision set up the Enemy Personnel Exploitation Section to manage and interrogate them. The Enemy Personnel Exploitation Section established a detention center, Camp Dustbin, first near Paris and later in Kransberg Castle outside Frankfurt. The US Joint Chiefs of Staff 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, 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 project was not initially targeted against the Soviet Union; rather the concern was that German scientists might emigrate and continue their research in countries that remained neutral during the war. Much US effort was focused on Saxony and Thuringia, which on July 1, 1945, became part of the Soviet occupation zone. Many German research facilities and personnel had been evacuated to these states before the end of the war, particularly from the Berlin area. The USSR then relocated more than 2,200 German specialists and their families—more than 6,000 people—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". News media revealed the program as early as December 1946.
On April 26, 1946, the Joint Chiefs of Staff issued directive JCS 1067/14 to General Eisenhower instructing that he "preserve from destruction and take under your control records, plans, books, documents, papers, files and scientific, industrial and other information and data belonging to... German organizations engaged in military research"; and that, excepting war-criminals, German scientists be detained for intelligence purposes as required.
Osenberg List
In the later part of World War II, Germany was at a logistical disadvantage, having failed to conquer the USSR with Operation Barbarossa, and its drive for the Caucasus. The failed conquest had depleted German resources, and its military–industrial complex was unprepared to defend the Greater Germanic Reich against the Red Army's westward counterattack. By early 1943, the German government began recalling from combat a number of scientists, engineers, and technicians to work in research and development to bolster German defense for a protracted war with the USSR. The recall from frontline combat included 4,000 rocketeers returned to Peenemünde, in northeast coastal Germany.The Nazi government's recall of their now-useful intellectuals for scientific work first required identifying and locating the scientists, engineers, and technicians, then ascertaining their political and ideological reliability. Werner Osenberg, the engineer-scientist heading the Wehrforschungsgemeinschaft, recorded the names of the politically cleared men to the Osenberg List, thus reinstating them to scientific work.
In March 1945, at Bonn University, a Polish laboratory technician found pieces of the Osenberg List stuffed in a toilet; the list subsequently reached MI6, who transmitted it to US intelligence. Then US Army Major Robert B. Staver, Chief of the Jet Propulsion Section of the Research and Intelligence Branch of the United States Army Ordnance Corps, used the Osenberg List to compile his list of German scientists to be captured and interrogated; Wernher von Braun, Germany's best rocket scientist, headed Major Staver's list.
Identification
In Operation Overcast, Major Staver's original intent was only to interview the scientists, but what he learned changed the operation's purpose. On May 22, 1945, he transmitted to the US Department of War Colonel Joel Holmes' telegram urging the evacuation to America of 100 of the 400 German scientists in his custody, as most "important for Pacific war" effort. Most of the Osenberg List engineers worked at the Baltic coast German Army Research Center Peenemünde, developing the V-2 rocket. After capturing them, the Allies initially housed them and their families in Landshut, Bavaria, in southern Germany.Beginning on July 19, 1945, the US Joint Chiefs managed the captured ARC rocketeers under Operation Overcast. However, when the "Camp Overcast" name of the scientists' quarters became locally known, the program was renamed Operation Paperclip in November 1945. Despite these attempts at secrecy, the press interviewed several of the scientists later that year.
Capture and detention
Early on, the United States created the Combined Intelligence Objectives Subcommittee. This provided the information on targets for the T-Forces that went in and targeted scientific, military, and industrial installations for their know-how. Initial priorities were advanced technology, such as infrared, that could be used in the war against Japan; finding out what technology had been passed on to Japan; and finally to halt research elsewhere.Von Braun and more than a thousand of his colleagues decided to surrender to Americans in 1945. One of the engineers later recalled their options: "We despise the French, we are mortally afraid of the Soviets, we do not believe the British can afford us. So that leaves the Americans." On June 20, 1945, they moved from the east closer to the American forces, to avoid the advancing Soviet army.
A project to halt the research was codenamed "Project Safehaven"; it was not initially targeted against the Soviet Union but addressed the concern that German scientists might emigrate and continue their research in countries that had remained neutral during the war. To avoid the complications involved with the emigration of German scientists, the CIOS was responsible for scouting and kidnapping high-profile individuals to block technological advancements in nations hostile to the US.
Much US effort was focused on Saxony and Thuringia, which on July 1, 1945, would become part of the Soviet Occupation zone. Many German research facilities and personnel had been evacuated to these states, particularly from the Berlin area. Fearing that the Soviet takeover would limit US ability to exploit German scientific and technical expertise, and not wanting the Soviet Union to benefit from it, the United States instigated an "evacuation operation" of scientific personnel from Saxony and Thuringia, issuing orders such as:
By 1947, this evacuation operation had netted an estimated 1,800 technicians and scientists and 3,700 family members. Those with special skills or knowledge were taken to detention and interrogation centers, such as one code-named "Dustbin" to be held and interrogated, in some cases for months.
A few of the scientists were gathered as a part of Operation Overcast, but most were transported to villages in the countryside where there were neither research facilities nor work; they were provided with stipends, and required to report twice weekly to police headquarters to prevent them from leaving. The Joint Chiefs of Staff directive on research and teaching stated that technicians and scientists should be released "only after all interested agencies were satisfied that all desired intelligence information had been obtained from them".
On November 5, 1947, the Office of Military Government, United States, which had jurisdiction over the western part of occupied Germany, held a conference to consider the status of the evacuees, the monetary claims that the evacuees had filed against the United States, and the "possible violation by the US of laws of war or Rules of Land Warfare". The OMGUS director of Intelligence Robert L. Walsh initiated a program to resettle the evacuees in the Third World, which the Germans referred to as General Walsh's Urwald-Programm ; but the program was not carried out. In 1948, the evacuees received settlements of 69.5 million Reichsmarks from the US, a settlement that soon became severely devalued during the currency reform that introduced the Deutsche Mark as the official currency of western Germany.
John Gimbel concludes that the United States held some of Germany's best minds for three years, therefore depriving the German recovery of their expertise.
