On the morning of June 2nd, 1948, seven men were hanged at Landsberg prison in Bavaria. Four of them were doctors. Karl Brandt, Hitler’s personal physician, tried to make a speech from the scaffold, but the hood was pulled over his head mid-sentence. The newspapers called it justice.
They were wrong. Of the doctors who built the Nazi medical system, almost none would ever see a courtroom. Some would be flown to America before the year was out. On December 9th, 1946, the doors of the Palace of Justice at Nuremberg opened for the second time in just over a year.
The International Tribunal that had judged Hermann Göring and Joachim von Ribbentrop was closed. What followed was an American military court, Military Tribunal 1, presided over by Judge Walter B. Beals of Washington. The first of 12 subsequent Nuremberg proceedings became known as the Doctors’ Trial.
In the dock stood 23 men. Twenty were trained physicians. Three were SS officials who had administered the medical machinery of the Reich. The lead defendant was Karl Brandt, a surgeon who had become Hitler’s escort physician in August 1934.
On September 1st, 1939, the same day Germany invaded Poland, Hitler appointed Brandt co-head of the T4 euthanasia program, which targeted patients classified as “life unworthy of life. ” By 1942, he was the Reich Commissioner for Health and Sanitation. For most of the war, Brandt lived inside Hitler’s circle. He kept a residence near the Berghof in the Bavarian Alps, where he and his wife Annie were regulars at Hitler’s evening table alongside Eva Braun, Albert Speer, and Heinrich Hoffmann.
The proximity protected him until the final days of April 1945, when Hitler learned that Brandt had moved his family west to surrender to the Americans rather than wait for the Soviets. A court in Berlin sentenced him to death. Himmler stalled the execution by demanding more witnesses. On May 2nd, with Hitler dead, Karl Dönitz released him.
The British arrested him three weeks later. Brigadier General Telford Taylor served as Chief of Counsel. His opening statement framed the charges: war crimes and crimes against humanity committed in the name of medical science. The defendants were accused of human experimentation in the camp system, of running the euthanasia program, and of SS membership.
Brandt’s defense amounted to a single argument: that in total war, personal ethics had to give way. Proceedings ran for 140 days, hearing 85 witnesses and admitting almost 1,500 documents. When the verdict came on August 20th, 1947, 16 defendants were convicted. Seven were sentenced to death, five to life imprisonment, four to 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 given 20 years, later commuted to 10. She would only serve five. On June 2nd, 1948, the death sentences were carried out at Landsberg Prison. 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 Landsberg Prison in 1952 to open a family medical practice in Stöcksey near Kiel. Out of the trial came the Nuremberg Code.
Two of the prosecution’s medical consultants, Andrew Ivy and Leo Alexander, had pressed throughout the proceedings for a written ethical standard that could outlive the courtroom. The verdict delivered one: 10 principles drafted in direct response to what witnesses had described—voluntary consent, scientific purpose, the participant’s right to walk out at any moment. It remains a foundational text in medical ethics worldwide. Few of the men who broke it would ever be punished.
But there is a number the Doctors’ Trial never accounts for. It tried 23 men. Historians estimate the number of German physicians directly involved in the camp experiments, the euthanasia program, and the wider racial hygiene apparatus ran into the hundreds, possibly the low thousands. Reich health leader Leonardo Conti and SS chief physician Ernst Robert Gravitz had 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. By the time Brandt walked to the scaffold, the man the world would soon call the Angel of Death was working as a farm hand in Bavaria, already planning his exit. Josef Mengele arrived at Auschwitz in May 1943. By November, he had been appointed chief physician of the Birkenau section, and for most of the next two years, he conducted experiments on prisoners, particularly twin children, under the cover of academic research.
When the Red Army closed in, Mengele simply walked away. Through 1945 and 46, he worked under his own name as a farm hand in Bavaria, in the same German state where the Doctors’ Trial would soon begin. In 1949, paid for by the family farm machinery business, he sailed for Argentina. He took citizenship 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 7th, 1979, he suffered a stroke while swimming in Bertioga and drowned. The grave was located in June 1985. DNA confirmed his identity in 1992.
He had eluded 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.
Same name, same credentials, no questions asked. In 1951, he applied for a hunting license under his real name, was recognized, and fled before East German 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 West German extradition requests. Only after Nkrumah was overthrown in February 1966 did Schumann return to Frankfurt for trial. The proceedings opened on September 23rd, 1970, were suspended in April 1971 for high blood pressure, and never reopened. He was released on July 29th, 1972, and died a free man in Frankfurt on May 5th, 1983.
Aribert Heim served only six weeks as an SS doctor at Mauthausen in late 1941. It was enough. The prisoners gave him a nickname: Dr. Death.
The young Austrian physician was captured by American troops on March 15th, 1945, processed through their 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 phoned home, 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 the next 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 10th, 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.
Heim spent 30 years in Cairo. Mengele spent 30 years on the move across South America. Other doctors took a far 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 bypass standard State Department vetting. The Joint Chiefs were already planning for war with the Soviet Union. Whatever these men knew, they could not be allowed to share it with Moscow.
The most successful Paperclip recruit in medicine was Hubertus Strughold. Throughout the war, Strughold had 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, then quietly cleared, then brought to the United States in August 1947, the same month the trial verdicts were being finalized.
He was made 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 the Apollo astronauts to the moon. The Aerospace Medical Association named its highest honor the Hubertus Strughold Award.
It was presented annually for 50 years. Strughold died at his Texas ranch on September 25th, 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 1st, 2013. Walter Schreiber took the unlikeliest route of all.
He came to America via a Soviet prison cell. 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 30th, 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 to a clandestine US Army interrogation center in Oberursel, Germany, a facility that would later feed into the CIA’s MK Ultra mind control program. On September 17th, 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. The 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 five years earlier.
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 41. 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 as a psychiatric expert witness in the Schleswig-Holstein state courts. Judges, professors, and senior officials knew exactly who he was.
Some of those 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 real identity surfaced only through a private quarrel in 1959. Heyde surrendered to Frankfurt police on November 11th of that year.
On February 13th, 1964, days before his trial opened, he hanged himself in his cell. His co-defendant Friedrich Tillman 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.
