Operation Paperclip was a classified U.S. government program that systematically recruited German and Austrian scientists, engineers, physicians, and technical specialists from the defeated Third Reich beginning in the summer and fall of 1945. Operated by the Joint Intelligence Objectives Agency (JIOA), which reported to the Joint Chiefs of Staff and worked closely with the Office of Strategic Services and later the Central Intelligence Agency, the program brought over 1,600 technical specialists to the United States to work for American military, intelligence, and civilian agencies during the critical period of the emerging Cold War and the American aerospace and weapons development programs.¹

Origins and the German Science Race

The program emerged from recognition, in the final stages of World War II, that Germany had developed technical capabilities - particularly in rocketry, jet propulsion, nerve agent chemistry, high-altitude medicine, and aeronautical engineering - that the United States had not matched. The V-2 ballistic missile program, developed at Peenemünde under Wernher von Braun and Walter Dornberger, represented a class of military technology that would define the postwar competition with the Soviet Union.

American forces operating under Operation Alsos raced German-held scientific facilities and personnel ahead of Soviet forces in the war's final weeks. The Soviets simultaneously conducted their own recruitment of German technical talent through Operation Osoaviakhim. The postwar division of Germany meant that both superpowers secured German expertise but that the competition produced parallel rocket and weapons programs in each country.¹

Authorization and the Nazi Problem

Annie Jacobsen wrote that President Harry S. Truman's initial directive specifically prohibited the recruitment of "ardent Nazis."¹ In practice, the JIOA systematically circumvented this prohibition: the records and backgrounds of scientists with disqualifying Nazi party membership, SS membership, or wartime conduct were altered before they were reviewed by the State Department and other agencies for security clearances. This process - which amounted to the systematic falsification of government records - was documented in Annie Jacobsen's 2014 investigation and in declassified JIOA files.

Von Braun, who was an SS officer and member of the Nazi party, had his records altered to enable his employment. Arthur Rudolph, who had used slave labor from the Mittelbau-Dora concentration camp in V-2 production - where approximately 20,000 prisoners died - was recruited and later directed the Saturn V rocket program for NASA before his Nazi-era conduct was investigated in the 1980s and he agreed to renounce U.S. citizenship and return to Germany. Hubertus Strughold, the Luftwaffe aviation medicine physician who became "the father of U.S. space medicine," had participated in or overseen human experiments at the Dachau concentration camp; his records were altered before his recruitment.¹

Acting Secretary of State Dean Acheson's memorandum to President Truman of August 30, 1946, "Interim Exploitation of German and Austrian Specialists in the United States," described the War Department project "Paperclip" and provided for expanding it to up to 1,000 specialists. It stated: "The War Department would be responsible for custody and for excluding from the program persons with Nazi or militaristic records." Truman's notation on it reads "approved 9/3/46."²

A set of Truman Library documents released in 2009 includes the screening terms of State-War-Navy Coordinating Committee 257/22, Appendix B, under which German specialists were to be brought to the United States. The commanding general of the United States Forces European Theater was to screen candidates on the basis of available records. A person found to have been a member of the Nazi Party and more than a nominal participant in its activities, or an active supporter of Nazism or militarism, could not be brought over under the terms. Position or honors awarded under the Nazi regime solely on account of scientific or technical ability did not by themselves disqualify a specialist. In doubtful cases the commanding general could transport the specialist to the United States for further interrogation and screening.³

Key Personnel

Von Braun was the most prominent Paperclip recruit. An SS officer and the technical director of the V-2 program, he was brought to Fort Bliss, Texas, along with more than 100 German rocket engineers, who arrived there near the end of 1945,⁴ and eventually directed the Marshall Space Flight Center and led the development of the Saturn V rocket that carried the Apollo program to the moon. The Army chronology states that von Braun's team had come to the United States under Operation Paperclip during 1945 and 1946.⁵ In April 1950 the team moved from Fort Bliss to Redstone Arsenal in Huntsville, Alabama. The Army chronology records a staff of Army officers and about 120 German scientists arriving at Redstone from Fort Bliss beginning on April 15, 1950, and the Ordnance Research and Development Division Sub-Office (Rocket) was redesignated the Ordnance Guided Missile Center on that date.⁶ The first missile work at the post was the Redstone missile, first flight tested on August 20, 1953.⁷ His wartime record, including his use of slave labor, was publicly documented during his lifetime but did not prevent his celebrated American career.

Walter Dornberger, who had commanded the Peenemünde facility, was also recruited, eventually working for Bell Aircraft on space plane concepts. Arthur Rudolph, who had managed V-2 production at Mittelwerk using Mittelbau-Dora camp labor, directed the Pershing missile and Saturn V programs before his wartime record was investigated by the Department of Justice's Office of Special Investigations in 1984; he renounced citizenship and departed rather than face proceedings.¹

In 1945, before the program was fully formalized, Qian Xuesen - the Chinese-American aerospace scientist who co-founded the Jet Propulsion Laboratory - was sent to Germany by the U.S. Army Air Forces on missions to interrogate captured German aerospace scientists, including von Braun and Peenemünde aerodynamicists, as part of the broader assessment of German technical capabilities.¹

Nazi Doctors and the CIA Behavioral Programs

Beyond the aerospace recruits, Paperclip transferred Nazi medical expertise that fed directly into the CIA's behavioral-control work. Kurt Blome, the Reich's deputy surgeon general and director of its biological-weapons program (including weaponized plague), was acquitted at the Nuremberg Doctors' Trial in August 1947 and within two months was consulting U.S. Army biological-warfare researchers in Maryland. Walter Schreiber, the Reich surgeon general who had assigned concentration-camp prisoners to experimental doctors, was given a post at the Air Force School of Medicine at Randolph Field, Texas. Kurt Plotner had conducted mescaline experiments on prisoners at Dachau for the SS in search of a truth drug, work of direct interest to the CIA's postwar truth-drug research. Camp King, the clandestine CIA-Army interrogation center in occupied Germany, served as the operational hub where this knowledge was applied; Schreiber and then Blome served as its chief medical officer, and the interrogation techniques developed there fed into Project Bluebird and Project Artichoke and the Project MKUltra programs. The chemist Friedrich "Fritz" Hoffmann, who had synthesized poison gases for the Luftwaffe, was likewise brought over.⁸

Legacy and Controversy

The German scientists brought through Paperclip made foundational contributions to the U.S. space program, missile development, aviation medicine, and chemical and biological research. Their technical contributions were real and in some cases irreplaceable. The ethical dimensions of the program - the employment of individuals with serious Nazi records, the systematic falsification of government records to circumvent legal prohibitions, and the implicit decision that American competitive advantage in the Cold War took priority over accountability for wartime crimes - remained subjects of historical and moral assessment.

The Soviet Union's parallel program produced the Soviet space and missile programs that competed directly with American programs developed from German expertise, creating a Cold War technological competition shaped on both sides by the same cohort of German scientists.⁹
