On the morning of June 2, 1948, seven men were hanged at Landsberg prison in Bavaria. Four were doctors. Karl Brandt, Adolf Hitler’s personal physician, tried to make a speech from the scaffold, but the hood was placed over his head mid-sentence. The newspapers called it justice, but the trial that condemned these men was only the beginning of a story that would continue for decades.

The Doctors’ Trial, formally known as Military Tribunal 1, opened at Nuremberg on December 9, 1946. It was the first of 12 subsequent proceedings held after the main International Military Tribunal had concluded. Presided over by Judge Walter B. Beals of Washington, the court brought 23 men to the dock: 20 trained physicians and three SS officials.
The lead defendant was Karl Brandt, a surgeon who had become Hitler’s escort physician in August 1934. On September 1, 1939, the same day Germany invaded Poland, Hitler appointed Brandt co-head of the T4 euthanasia program, which targeted patients deemed unworthy of life. By 1942, he was Reich Commissioner for Health and Sanitation. Brandt’s proximity to Hitler protected him for most of the war, but in late April 1945, Hitler learned that Brandt had moved his family west to surrender to the Americans rather than wait for the Soviets.
A Berlin court sentenced him to death, though SS chief Heinrich Himmler stalled the execution by demanding more witnesses. After Hitler’s death, Karl Dönitz released Brandt. The British arrested him three weeks later. Prosecutor Telford Taylor framed the charges as war crimes and crimes against humanity committed in the name of medical science.
The defendants were accused of human experimentation in the camp system, running the euthanasia program, and SS membership. Brandt’s defense argued that in total war, personal ethics had to give way. The proceedings ran for 140 days, hearing 85 witnesses and admitting nearly 1,500 documents. On August 20, 1947, 16 defendants were convicted.
Seven received death sentences, five received life imprisonment, and four received prison terms of 10 to 20 years. Herta Oberheuser, the only female doctor in the dock, was convicted for her role in the Ravensbrück experiments and sentenced to 20 years, later commuted to 10. She served only five. The executions were carried out at Landsberg Prison on June 2, 1948.
Karl Brandt was hanged alongside Viktor Brack, Rudolf Brandt, Karl Gebhardt, Waldemar Hoven, Joachim Mrugowsky, and Wolfram Sievers. The other convicts began an early return to civilian life almost immediately. Allied review boards commuted most prison terms during the first half of the 1950s. Oberheuser walked out of prison in 1952 and opened a family medical practice near Kiel.
Out of the trial came the Nuremberg Code. Two of the prosecution’s medical consultants, Andrew Ivy and Leo Alexander, had pushed throughout the proceedings for a written ethical standard. The verdict delivered one: 10 principles drafted in response to what witnesses had described, including voluntary consent, scientific purpose, and the participant’s right to withdraw. The code remains a foundational text in medical ethics worldwide.
But the trial tried only 23 men. Historians estimate that the number of German physicians directly involved in the camp experiments, the euthanasia program, and the broader racial hygiene apparatus ran into the hundreds, possibly the low thousands. Many escaped justice entirely. Reich health leader Leonardo Conti and SS chief physician Ernst Robert Gravitz ended their own lives in the final days of the war.
Theodor Morell, who had treated Hitler daily since 1936, died of a stroke a week before Brandt reached the gallows. Others took far longer to confront, or simply never did. By the time Brandt walked to the scaffold, the man the world would soon call the Angel of Death was working as a farmhand in Bavaria. Josef Mengele arrived at Auschwitz in May 1943 and was appointed chief physician of the Birkenau section by November.
For most of the next two years, he conducted experiments on prisoners, particularly twin children. When the Red Army closed in, he walked away. Through 1945 and 1946, Mengele worked under his own name as a farmhand in Bavaria. In 1949, funded by his family’s farm machinery business, he sailed for Argentina.
He became a citizen there as Jose Mengele in 1956, relocated to Paraguay in 1959, then fled to Brazil in October 1960 after Mossad seized Adolf Eichmann from a Buenos Aires street. He spent the rest of his life near São Paulo under the name Wolfgang Gerhard. On February 7, 1979, he suffered a stroke while swimming and drowned. The grave was located in June 1985, and DNA confirmed his identity in 1992.
He had evaded justice for 34 years. Horst Schumann’s escape took a different shape. He had headed the Grafeneck euthanasia center from January 1940 and arrived at Auschwitz in July 1941, where he ran X-ray sterilization experiments on Jewish prisoners. From April 1946, he worked openly as a municipal sports doctor in Gladbeck, using his real name with no questions asked.
In 1951, he applied for a hunting license under his real name, was recognized, and fled before authorities could move on the warrant. He surfaced in Sudan in 1955, running a hospital, where a German journalist photographed him and called him a second Albert Schweitzer. A survivor identified him in 1962. He fled again through Nigeria and Libya to Ghana, where President Kwame Nkrumah personally refused extradition requests.
Only after Nkrumah was overthrown in February 1966 did Schumann return to Frankfurt for trial. The proceedings opened on September 23, 1970, but were suspended in April 1971 for high blood pressure and never reopened. He was released on July 29, 1972, and died a free man in Frankfurt on May 5, 1983. Aribert Heim served only six weeks as an SS doctor at Mauthausen in late 1941.
It was enough. Prisoners gave him the nickname Dr. Death. Captured by American troops on March 15, 1945, he was processed through the POW system and released.
For the next 17 years, he built a respectable practice as a gynecologist in Baden-Baden. In 1962, a West German court issued a warrant. Heim was warned that police were waiting and disappeared. He drove south through France and Spain, crossed into Morocco, transited Libya, and surfaced in Cairo.
He converted to Islam, took the name Tarek Farid Hussein, and lived in a small hotel in the city center for three decades. The Simon Wiesenthal Center eventually placed him at the top of its most wanted list. Heim died of intestinal cancer in Cairo on August 10, 1992, the day after the Barcelona Olympics ended. His son Rüdiger was at his bedside.
The family kept the secret for 17 more years. Only in February 2009 did Süddeutsche Zeitung and The New York Times uncover the truth. A Baden-Baden court formally confirmed his death in 2012. Mengele spent 30 years on the move across South America.
Heim spent 30 years in Cairo. Other doctors took an easier route: they boarded ships chartered by the country that had just defeated them. In September 1946, President Truman authorized Operation Paperclip, a program that would eventually bring roughly 1,600 German scientists and physicians to the United States. The paperclip on a personnel file meant standard State Department vetting was bypassed.
The Joint Chiefs were planning for war with the Soviet Union, and whatever these men knew could not be allowed to fall into Moscow’s hands. The most successful Paperclip recruit in medicine was Hubertus Strughold. Throughout the war, he served as chief of aeromedical research at Göring’s Ministry of Aviation, overseeing the field that produced the Dachau low-pressure chamber experiments. Several of his subordinates were defendants at the Doctors’ Trial.
Strughold himself was investigated, quietly cleared, then brought to the United States in August 1947, the same month the trial verdicts were being finalized. He became professor of space medicine at the US Air Force School of Aerospace Medicine in San Antonio. In 1950, he co-founded the Space Medicine branch of the Aerospace Medical Association. His work shaped the space suit and life support systems that carried Apollo astronauts to the moon.
The Aerospace Medical Association named its highest honor the Hubertus Strughold Award, presented annually for 50 years. Strughold died at his Texas ranch on September 25, 1986. Only in 2004 did a German investigation produce new evidence linking him to the Dachau research, and the award was finally discontinued on October 1, 2013. Walter Schreiber took the unlikeliest route of all.
Surgeon General of the Third Reich and a major general in the Wehrmacht Medical Service, Schreiber was captured by Soviet forces in Berlin on April 30, 1945, and held in Moscow’s notorious prison. In August 1946, the Soviets produced him as a surprise witness at the main Nuremberg trial, where his testimony helped implicate Kurt Blome in biological weapons research. In October 1948, his daughter made contact with him from the West. He took a train from Dresden to Berlin, walked into the Allied Control Authority offices in the American sector, and asked for asylum.
The Americans took him. By 1949, he was post physician at a clandestine US Army interrogation center in Oberursel, a facility that would later feed into the CIA’s MK Ultra program. On September 17, 1951, Schreiber arrived in New York aboard the USNS General Maurice Rose, listed on the manifest as a paperclip. He was assigned to the Air Force School of Aviation Medicine at Randolph Field, Texas.
Columnist Drew Pearson exposed him in October 1951. A Ravensbrück survivor named Yanina Iwanowska identified him in February 1952 to Dr. Leo Alexander, one of the men who had helped write the Nuremberg Code. American intelligence officers quietly arranged Schreiber’s relocation to Argentina, where he worked as an epidemiologist until his death in 1970.
The strangest case unfolded inside West Germany itself. Werner Heyde had directed the T4 euthanasia program from 1939 to 1941. A German court sentenced him to death in absentia in 1946. In 1947, he slipped from the back of a US Army truck taking him to Nuremberg for interrogation, made his way north to Flensburg, and began practicing medicine under the name Dr.
Fritz Sawade. For 13 years, he worked as a sports physician and psychiatric expert witness in the Schleswig-Holstein state courts. Judges, professors, and senior officials knew exactly who he was. Some judges used him as an expert witness for years.
His wife had him declared legally dead in 1952 and collected a widow’s pension for the next seven years. His identity surfaced only through a private quarrel in 1959. Heyde surrendered to Frankfurt police on November 11 of that year. On February 13, 1964, days before his trial opened, he hanged himself in his cell.
His co-defendant Friedrich Tillmann fell from a Cologne office building the morning before. Seven hanged at Landsberg. Hundreds were never charged. The Doctors’ Trial gave the world the Nuremberg Code, 10 principles of medical ethics every medical school still teaches.
What it did not give the world was a reckoning. Most of the men who broke those rules died in their own beds, decorated, retired, and mourned. A few were promoted.
