Operation Paperclip

From July 20, 1945 through the early 1950s, U.S. intelligence services executed Operation Paperclip — initially code-named Operation Overcast and also designated Project Paperclip — a classified United States program to recruit, exploit, and relocate more than 1,600 German scientists, engineers, and technicians in the aftermath of World War II. The program was authorized by the Joint Chiefs of Staff and administered by the Joint Intelligence Objectives Agency (JIOA), a subcommittee of the Joint Intelligence Committee governed from an office in the "E" ring of the Pentagon. By 1955 nearly 1,000 German scientists had received U.S. citizenship and been placed in leading positions across the military-industrial complex; according to journalist Linda Hunt, the program ran in various forms until 1973 — far longer than officially acknowledged — making it "the biggest, longest-running operation involving Nazis in our country's history." Researchers including Joseph P. Farrell and Jim Marrs argue that beyond conventional rocketry and aerospace expertise, the program's deepest prize was access to Nazi secret weapons of a more exotic character — technology that some allege originated from, or was influenced by, non-human sources — and that this knowledge flowed directly into the covert stratum of the postwar secret space program.

Origins and authorization

The American rocket-intelligence effort predated the program's formal establishment. Colonel Gervais William Trichel, first chief of the newly created Rocket Branch inside U.S. Army Ordnance, assembled a team — "Special Mission V-2" — to locate and exploit German rocket science in occupied Europe, recognizing the United States was roughly twenty years behind Germany in rocket development. Major Robert B. Staver was among the first intelligence officers inside the Harz Mountains tunnel complex after liberation and would play a central role in recruiting Wernher von Braun's circle.

On May 19, 1945 — twelve days after Germany's unconditional surrender — Herbert Wagner, creator of the first Nazi guided missile used in combat, landed in Washington, D.C. aboard a U.S. military aircraft with blacked-out windows. The program was formally approved by the Joint Chiefs of Staff on July 20, 1945 under the code name Operation Overcast and initially envisaged as a temporary measure to support the ongoing Pacific war effort and postwar U.S. military research. Von Braun and more than seven hundred other Nazi rocket scientists were among the early arrivals by mid-November 1945. The first group of seven rocket scientists — von Braun, Erich Neubert, Theodor Poppel, August Schulze, Eberhard Rees, William Jungert, and Walter Schwidetzky — signed the earliest Overcast contracts and arrived at Fort Strong, a disused Civil War–era coastal fortification in Boston Harbor, in September 1945.

President Harry Truman had authorized the program on the explicit assurance that no one with "Nazi or militaristic records" would be included — an assurance systematically violated. Overcast was renamed Paperclip in early 1946 after the original code name was reportedly compromised — German scientists' families had begun referring to their U.S. military housing as "Camp Overcast." The new name arose from a workaround in which Army Intelligence officers would discreetly attach a paperclip to the security files of the more troublesome Nazi scientists, flagging them for delayed State Department review so that they could remain longer under military custody.

Annie Jacobsen's archival investigation established that the program was never a narrow rocket-recruitment exercise: of twenty-one scientists she profiles, eight — including Otto Ambros, Theodor Benzinger, Kurt Blome, Walter Dornberger, Siegfried Knemeyer, Walter Schreiber, Walter Schieber, and Wernher von Braun — had at some point worked directly alongside Adolf Hitler, Heinrich Himmler, or Hermann Göring; fifteen were dedicated Nazi Party members; ten were members of the SA or SS; and six stood trial at Nuremberg, one of whom was convicted of mass murder and slavery, received clemency, and was subsequently hired by the U.S. Department of Energy.

Program structure

The Paperclip field office operated initially from Heidelberg under the intelligence division of the U.S. Army's European Command, headed by Deputy Director Colonel Robert Schow. Interrogation and initial exploitation of captured German scientists was conducted at Camp Dustbin, an Allied detention center relocated from outside Paris to Kransberg Castle — an estate near Frankfurt that had been refurbished for Hitler's architect Albert Speer in 1939 with a twelve-hundred-square-foot underground bunker complex and poison-gas air locks. JIOA officers systematically altered Office of Military Government for Germany (OMGUS) security dossiers, changing assessments from "ardent Nazi" to "not an ardent Nazi," so that recruits could clear State Department vetting. Hunt later examined more than 130 Paperclip security reports and found that every single one had been changed to eliminate the security-threat classification.

The Osenberg List — a master index of Germany's politically-cleared scientists compiled by Werner Osenberg, head of the Wehrforschungsgemeinschaft (Defense Research Association) — became the skeleton of the American recruitment programme. Fragments of the list were reportedly discovered by a Polish laboratory technician at Bonn University in a toilet in early 1945 and passed to British intelligence, which forwarded them to Samuel Goudsmit of Operation Alsos; Osenberg himself was interrogated and directed Alsos agents to where the remaining papers had been buried.

After Allen Dulles assumed control of the newly created CIA, he deepened the program's integration with a broader Council on Foreign Relations-linked intelligence network. Peter Levenda, tracing the corporate-intelligence overlap, describes how American corporations including AT&T, IBM, and Standard Oil operated openly within Nazi Germany during the war through international subsidiaries, and how the Bush family's Union Banking Corporation was shut down under the Trading with the Enemy Act in 1942 for continuing this commerce after the U.S. had declared war — yet without prosecution: "There was no way to stop the American involvement of the involvement of American industry and economic institutions with Nazi Germany. It was pervasive. It was everywhere." Nazi spymaster Reinhard Gehlen cut a separate deal: he transferred his Eastern European intelligence network to the CIA in exchange for the non-prosecution of his operatives' Nazi pasts, and his cooperation enabled further sanitization of Paperclip dossiers. The resulting organization — the Gehlen Organization — became the nucleus of West Germany's postwar BND intelligence service.

The Mittelwerk context

The scientific prize the United States was negotiating over had been produced, in large part, inside the Mittelwerk — a subterranean V-weapon factory in the Harz Mountains staffed by concentration-camp slaves from Dora and its thirty subcamps. In the first six months of tunnel construction alone, 2,882 laborers died; SS Brigadier General Hans Kammler instructed his staff to "pay no attention to the human victims." Mittelwerk general manager Georg Rickhey, von Braun, Dornberger, and Arthur Rudolph held a meeting on May 6, 1944 at which it was decided the SS should enslave another eighteen hundred skilled French workers to fill the shoes of those worked to death — the surviving record indicates none of the three objected. On August 15, 1944 von Braun himself wrote to Mittelwerk engineer Albin Sawatzki requesting that detainees from Buchenwald be transferred to the Mittelwerk: "I immediately looked into your proposal by going to Buchenwald [myself]... I have arranged their transfer to the Mittelwerk with Standartenführer [Colonel] Pister, [the commandant of Buchenwald]." Von Braun visited the underground tunnels in an official capacity ten times during the winter of 1944–45 and had been promoted that March to SS-Sturmbannführer (SS major) as head of the Mittelbau-Dora Planning Office.

Key figures

Von Braun, described in SS records as an SS major and a personal friend of Heinrich Himmler, was accused by concentration-camp survivors of ordering the execution of slave laborers at the Mittelwerk V-2 factory. Walter Dornberger — charged as a war criminal for the V-2 rocket bombardments of London and Antwerp but never prosecuted — entered the United States under Paperclip and became a vice president of Bell Helicopter. Arthur Rudolph, head of Mittelwerk V-2 production, was named project director of the Saturn V rocket program at NASA's Marshall Space Flight Center; he was eventually stripped of his U.S. citizenship in 1983 after conceding to the Department of Justice that he had "participated under the direction of and on behalf of the Nazi government of Germany, in the persecution of unarmed civilians because of their race, religion, national origin, or political opinion." Kurt Debus, first director of the Kennedy Space Center, was an SS and SA member who in 1942 reported a colleague to the Gestapo for making anti-Hitler remarks. The Peenemünde team at NASA's Marshall Center replicated, nearly structure for structure, the wartime V-2 research organization — holding "the chief and deputy slots of every major division and laboratory."

Other notable recruits included Hubertus Strughold, the "father of space medicine," whose wartime research has been linked to lethal experiments on prisoners; physicist Werner Heisenberg, Nobel laureate and head of the Nazi atomic research program; chemical-weapons specialist Otto Ambros, who was arrested on January 17, 1946 after leaving the French zone and interrogated at Dustbin before being turned over to the Nuremberg jail; biological warfare specialist Kurt Blome, whose "dark tale of plans for biological warfare spearheaded by Heinrich Himmler" emerged at Dustbin; and Third Reich surgeon general Walter Schreiber, brought in under so-called Accelerated Paperclip, a relaxation permitting recruits previously classified as undesirable.

Exotic technology recruits: Neugebauer and Schumann

Henry Stevens, in Hitler's Flying Saucers (2003), identifies two specific Paperclip recruits whose recruitment was allegedly connected to advanced technology far beyond conventional rocketry. Dr. Franz J. Neugebauer — the "foremost German authority" on the effect of power-plant weight on flight economy, who had held leading positions at Junkers in Dessau and Munich from 1924 to 1943 and directed the Institute for Aeronautical Research at Munich through 1945 — was brought to Wright Field's Intelligence (T-2) division, where his real expertise was reportedly not diesel engines but knowledge of how heavy power plants (such as nuclear reactors) affected aircraft performance and economy — a skill directly relevant to the emerging American atomic aircraft programme.

Stevens also identifies Dr. W.O. Schumann — co-inventor of the Schumann resonance and a pre-war evaluator of the Hans Coler free-energy device — as another Paperclip acquisition, whose stated postwar role was improving American submarine communications through antenna design, though Stevens notes he was "no stranger to alleged free energy devices" given his 1926 confirmation of the Coler device's apparently genuine operation.

Relationship to parallel and successor programs

Paperclip sat within a cluster of overlapping initiatives. Operation Safehaven, conducted in parallel from 1944 onward, was aimed at preventing Nazi assets — including scientific personnel — from escaping Allied-occupied Germany via neutral countries. The Soviet counterpart, Operation Osoaviakhim, was executed in a single night (October 22, 1946) and relocated more than 2,200 German specialists and their families — over 6,000 people in total — to the USSR, targeting the same research fields as the American program.

Paperclip itself spawned a series of successor and parallel efforts. The National Interest program, tightly linked to the CIA, bypassed anti-Nazi elements within military intelligence and extended recruitment to Eastern European ex-Nazis deemed useful against the Soviets, and to convicted war criminals. Project 63 was designed specifically to extract German scientists from Europe before the Soviets could recruit them; by 1957 more than sixty companies — including Lockheed, Martin Marietta, and Bell Laboratories — appeared on JIOA recruitment rosters. When West German officials complained to U.S. Ambassador James Conant and demanded Paperclip be ended, the program was simply renamed the Defense Scientists Immigration Program (DEFSIP). After the Soviet launch of Sputnik in October 1957, demand for the Nazi scientists intensified further.

Yale University, Duke University, the University of Texas, and Boston University, among others, received Paperclip scientists as employees; German recruits could obtain security clearances more easily than American scientists, making them attractive to defense contractors working on classified projects.

Exotic technology and the fringe dimension

Farrell argues in Reich of the Black Sun (2004) that the Nazi secret weapons research overseen by SS-Obergruppenführer Hans Kammler — whose Kammlerstab "think tank" operated behind a triple belt of counterintelligence so effective that neither U.S., British, nor Soviet intelligence ever fully penetrated it — represented a generation of technology beyond conventional rocketry. Kammler's command allegedly encompassed all German secret weapons research, V-1 and V-2 operations, and the world's first underground missile testing facility, and Farrell contends the technology he controlled disappeared from Allied accounting at war's end — possibly surfacing, in altered form, within American black programs.

Farrell further argues that the MJ-12 documents, if genuine, suggest a connection between Paperclip's acquisition of exotic Nazi technology and the Roswell incident of 1947: certain technical language in the documents, he contends, "describes something simultaneously both very advanced" and consistent with advanced aerodynamic research conducted at Peenemünde. His conclusion is not that the technology was extraterrestrial, but that at least some of what has been attributed to a non-human origin may represent captured or reverse-engineered Nazi advanced technology — while allowing that an ET layer of disinformation may also be operative.

Marrs identifies the NSC's covert science-and-technology subcommittee — linked to Majestic 12 — as the node where "control over rocketry, space, alternative energy sources, and even UFOs" was allegedly coordinated alongside the Paperclip scientists, with Allen Dulles and the globalist networks managing both tracks simultaneously.

The Rosin warning

Carol Rosin, an aerospace executive who worked closely with von Braun during his final years, gave an affidavit to the Disclosure Project describing a recurring warning von Braun gave her: that a sequence of manufactured enemies — Russians, terrorists, third-world dictators, asteroids, and finally aliens — would be used to justify the militarization of space, and that "the last card is the alien card." Farrell notes that a Paperclip "specialist" speaking in the early 1970s with such prescience about the sequence of official enemies implies von Braun was "a senior insider, privy to the plots and canards of the innermost conspiracies driving western politics and culture."

A parallel space program

Marrs documents communication between Paperclip scientists in the United States and their former colleagues working for the Soviets — facilitated by the same interconnected banking and business interests that had financed both the Nazi Reich and Soviet communism — and reports that the von Braun team received orders to halt rocket development in the mid-1950s, deliberately held in a "holding pattern" while the Soviets caught up. This leads Marrs to conclude — drawing on Farrell — that the space race was purportedly not a genuine competition between the U.S. and the USSR, but "a combined space program run by Nazi scientists and controlled by high-level globalists," with a covert third track operating beneath both public programs.

Kammlerstab as the organizational model

Joseph Farrell, speaking with Forum Borealis, argues that the Kammlerstab — Kammler's secret think tank inside the Skoda Works at Pilsen — was not merely a source of scientists for Paperclip but the organizational model that the U.S. replicated wholesale: the triple belt of counterintelligence, the compartmentalized internal circulation of classified papers, and the centralization of all exotic research in one protected institution were all features that the incoming Nazi scientists brought with them and that manifested in DARPA. Farrell calls DARPA essentially the postwar American reduplication of the Kammlerstab: "They bring with them not only their ideology, but they bring with them their organization. I think we picked up on this Kammler amount of secrecy and organization and centralization that surrounded this thing and we simply reduplicated it in the United States."

Farrell further notes that Paperclip files were reportedly not held at the National Archives but at specific air bases — Wright-Patterson in Dayton, Ohio and Maxwell in Alabama — a classified storage arrangement that persisted until the early 1990s. The critical declassification wave came at the very end of the first Bush administration, when the Zinsser affidavit (a German pilot's 1944 description of what appears to be a Nazi nuclear test over the Baltic Sea, made to American interrogators in October 1944) was finally released — directly implicating the Paperclip concealment strategy as having extended not merely to the scientists but to evidence of Nazi weapons achievements that made Paperclip's scale and secrecy geopolitically necessary.

Paperclip scientists and the Roswell retrieval

Researcher Donald Schmitt, in a 2023 interview with Dr. Michael Salla, described testimony from the family of Ernst Steinhoff — a rocket scientist who worked directly under Wernher von Braun — indicating that a number of Paperclip scientists were brought to Roswell Army Air Field at significant political risk to examine the debris recovered in July 1947. Schmitt argued that the decision to expose Paperclip scientists to the retrieval material was itself evidence that the material was not a weather balloon: "Why in God's name would you bring the Nazi scientists in to look at pieces of a weather balloon? I'm sorry, major disconnect. They brought the scientists at high risk, exposing them to this. And then beyond that, they also brought them over to Wright-Patterson in Dayton, Ohio for the same reasons — to become part of these crash retrieval cases, not only the wreckage, but also the bodies, because they wanted to make sure that this wasn't something that the Germans were experimenting with." Salla and Schmitt both noted that Wright-Patterson was simultaneously the primary base for Paperclip scientists working on non-rocket advanced technology and the primary receiving facility for the Roswell wreckage and bodies — making the two programs geographically and institutionally inseparable from 1947 onward.

Paperclip infiltration of biomedical and pharmaceutical institutions

Dan Willis, testifying in a 2023 episode of Exopolitics Today, cited William Tompkins's direct account that Paperclip scientists "took over the aerospace and biomedical operations within the U.S." — identifying Scripps Research in La Jolla, California as the first major institution allegedly subject to what Tompkins called a "Nazi biomedical takeover," with the highest positions within the U.S. pharmaceutical industry eventually passing into their control. Tompkins had worked at TRW from 1967 to 1971 on programs that included, by his account, developing pharmaceutical cocktails for age regression, and reported that Scripps Institute was conducting related experiments. Salla noted that this represented Tompkins's direct firsthand exposure to how Paperclip scientists had "infiltrated top aerospace and biomedical research institutions." Willis also cited Paperclip as part of a longer strategy described in terms of "Worldview Warfare" — the MKUltra-era plan to "create a matrix of perception to control our media, control our education, control Hollywood" and suppress public knowledge of advanced technologies, tracing this strategy directly to Allen Dulles and the incoming Nazi-linked network within the CIA.

True scale of the program

William Tompkins, who worked in Naval Intelligence during and after the war, described Operation Paperclip as far larger than publicly acknowledged. According to Tompkins, "Paperclip was not just ten or twelve German fellows coming here. It was a massive number." He further testified that "Von Braun and Debus were both principals in that organization in Germany" before their arrival in the United States, having already been "managing construction of extraterrestrial Space craft carriers" underground in Germany during the war. According to Tompkins, only about 5% of the German scientific organization came to the United States, while the majority was allegedly relocated to Antarctica before the war's end.

Tompkins characterized NASA as "maybe the 1st place that's infiltrated by Nazis and that ideology," emphasizing that the German scientists brought not only their technical knowledge but their organizational methods and ideological framework to American aerospace programs.

Von Braun and crimes against humanity

Joe Rogan, in a 2025 conversation with journalist Danny Jones about journalist Annie Jacobsen's book on Paperclip, stated that the Simon Wiesenthal Center had concluded that if Wernher von Braun were alive today he would face prosecution for crimes against humanity. Rogan described a specific practice at von Braun's wartime rocket factory: "When he was running his rocket factory in Berlin, he would take the five slowest Jews and hang them from the front of the factory. So that as you're walking in, this is what happens if you move slowly. And that was the head of NASA who supposedly got us to the moon." Jones, describing Jacobsen's fieldwork in Germany, noted that she located the grandson of one of the Paperclip recruits — who "detested his father with every fiber of his being" — and showed him private letters the scientist had written to his family from America, revealing that the man had been "torn between being this scientist contracted to do all this crazy shit for America" while his family remained in Germany.

Jacobsen's archival work further documented the program's preparedness posture: within one year of the atomic bombings of Hiroshima and Nagasaki, the Joint Intelligence Committee had warned the Joint Chiefs of Staff to prepare for "total war" with the Soviets — including atomic, chemical, and biological warfare — with an estimated start date of 1952. Paperclip, she concluded, left behind "a legacy of ballistic missiles, sarin gas cluster bombs, underground bunkers, space capsules, and weaponized bubonic plague."
