The two Treblinka trials concerning the Treblinka extermination camp personnel began in 1964. Held at Düsseldorf in West Germany, they were the two judicial trials in a series of similar war crime trials held during the early 1960s, such as the Jerusalem Adolf Eichmann trial (1961) and the Frankfurt Auschwitz Trials (1963–65), as a result of which the general public came to realize the extent of the crimes that some two decades earlier had been perpetrated in occupied Poland by Nazi bureaucrats and their willing executioners. In the subsequent years, separate trials dealt with personnel of the Bełżec (1963–65), Sobibor (1966), and Majdanek (1975–81) extermination camps.
In 1946 Josef Hirtreiter was arrested in the course of the Allied investigations into the killing of disabled persons in the Hadamar Euthanasia Centre. Although not focused on Treblinka from the beginning, and not serving as an upbeat to the later Treblinka trials, the Hirtreiter trial is viewed by some historians as being part of these. Hirtreiter could not be shown to have been criminally involved at Hadamar; however, he did confess to having worked in a camp near the Polish village of Małkinia where Jews were killed in a gas chamber. Further investigations showed that Hirtreiter had been stationed at the Treblinka extermination camp, where he supervised the victims' disrobement prior to their gassing. He was charged with participation in the mass-murder of Jews, particularly the killing of more than 10 persons, including infants. On 3 March 1951 Hirtreiter was sentenced to life imprisonment (released in 1971).
The crimes committed in the General Government territory of occupied Poland were investigated by the Central Agency from July 1959 by the German specialist in the Nazi prosecution Dietrich Zeug, present at the Eichmann trial. His inquiry led to the first arrest of Treblinka deputy commandant on December 2, 1959. Zeug received survivor testimonies from Yad Vashem which allowed him to examine German national archives for more clues. He was the first to establish the chain of command for Operation Reinhard.
The first Treblinka trial began on 12 October 1964 and concerned eleven members of the SS camp personnel, or about a quarter of the total number of SS employed in the extermination of Jews brought aboard Holocaust trains to Treblinka. More than 100 witnesses were called, with incriminating evidence presented by Franciszek Ząbecki, a dispatcher employed by the Reichsbahn during the Holocaust train departures from across occupied Poland, proven by original German waybills he collected. The verdicts were pronounced on 3 September 1965:
|Kurt Franz||SS-Untersturmführer||Deputy commandant||Life imprisonment||Served 28 years, released, lived another 5 years|
|Otto Richard Horn||SS-Unterscharführer||Totenlager – Corpse detail||Acquitted|
|Erwin Lambert||SS-Unterscharführer||Built Large Gas Chambers||4 years imprisonment||Time served. Died 1976|
|Heinrich Matthes||SS-Scharführer||Chief of Totenlager||Life imprisonment|
|Willi Mentz||SS-Unterscharführer||Lazarett ("Infirmary," which actually meant shooting victims)||Life imprisonment||Released in 1978 and died 3 months later|
|August Miete||SS-Unterscharführer||Lazarett – "Angel of Death"||Life imprisonment||Possibly released in the mid 1980s.|
|Gustav Münzberger||SS-Unterscharführer||Totenlager – Gas Chambers||12 years imprisonment||Served 6 years, released on good behavior, lived another 6 years|
|Albert Rum||SS-Unterscharführer||Totenlager – Gas Chambers||3 years imprisonment|
|Otto Stadie||SS-Stabsscharführer||Camp Administration||6 years imprisonment||Released early due to poor health, lived about another decade|
|Franz Suchomel||SS-Unterscharführer||Gold and Valuables||7 years imprisonment||Served 4 years, released, lived another 10 years|
|Kurt Küttner||SS-Oberscharführer||Lower camp of Treblinka II||Died before trial|
The second Treblinka trial also known as the Stangl trial, was held from 13 May to 22 December 1970, five years after the first group trial for war crimes. In this trial, camp commandant Franz Stangl, expelled three years earlier from Brazil, finally stood accused. Stangl had previously assisted in killing handicapped people during Operation T4 (the Euthanasia Programme of the National Socialists), and, before moving on to Treblinka, had been the first commandant of Sobibor. Under his supervision, most of the Treblinka killings took place. He was sentenced to life imprisonment, and died in prison on 28 June 1971, during the appeal case.
