Rudolf Franz Ferdinand Höss was the Nazi commandant of the Auschwitz extermination camp.

Höss (born November 25, 1900; died April 16, 1947) was born in Baden-Baden, a town in southwest Germany. In high school, he trained for the priesthood yet his father's death and the outset of World War I changed those career plans. In 1916, he joined the German army where he would be wounded three times and was twice awarded the Iron Cross. In 1920, Hoss joined the East Prussian Free Corps (Freikorps) and took part in the suppression of disturbances in Latvia and in quelling workers who were staging a revolt in the Ruhr. It was through the Freikorps, in early 1922, that Hoss was first introduced to Adolf Hitler.

Hoss immediately joined the Nazi Party and renounced his affiliation with the Catholic Church. When France and Belgium entered and occupied the Upper Rhine region in January 1923, Höss participated in the assassination of Freikorpsman Walter Kadow and was captured and sentenced to 10 years in prison. He was released in 1928 as part of the general amnesty.

In 1933, Hoss joined the SS and in 1934 he was attached to the SS at Dachau. On August 1, 1938, Hoss was appointed as adjutant of the Sachsenhausen concentration camp until his appointment as Kommandant of the newly-built camp at Auschwitz in early 1940.

In May 1941, SS commander Heinrich Himmler told Höss that Hitler had given orders for the final solution of the Jewish question and that "I have chosen the Auschwitz camp for this purpose." Höss converted Auschwitz into an extermination camp and installed gas chambers and crematoria that were capable of killing 2,000 people every hour. Counting corpses with the cool dedication of a trained bookkeeper, he went home each night to the loving embrace of his own family who lived on the camp grounds.

Watching millions of innocent human beings dissolve in the gas chambers, burn in the crematoriums and their teeth melt into gold bars, Höss wrote poetry about the "beauty" of Auschwitz.

Nazi leader Adolf Eichmann recounted in his memoirs how he was assigned in early 1942 to visit the Auschwitz death camp and report back to superiors on the killing of Jews. He wrote that the methods for killing were still crude, but these represented a gruesome foretaste of the factory-style gas chambers and crematoria that were to follow:

"Höss, the Kommandant, told me that he used sulfuric acid to kill. Round cotton wool filters were soaked with this poison and thrown into the rooms where the Jews were assembled. The poison was instantly fatal. He burned the corpses on an iron grill, in the open air. He led me to a shallow ditch where a large number of corpses had just been burned."

Höss eventually found that gassing by carbon monoxide was inefficient and introduced the cyanide gas Zyklon B. He later recalled:

"The gassing was carried out in the detention cells of Block 11. Proctected by a gas mask, I watched the killing myself. In the crowded cells, death came instantaneously the moment the Zyklon B was thrown in. A short, almost smothered cry, and it was all over... I must even admit that this gassing set my mind at rest, for the mass extermination of the Jews was to start soon, and at that time neither Eichmann nor I was certain as to how these mass killings were to be carried out. It would be by gas, but we did not know which gas and how it was to be used. Now we had the gas, and we had established a procedure."

Auschwitz became the killing centre where the largest numbers of European Jews were killed. After an experimental gassing there in September 1941 of 850 malnourished prisoners, mass murder became a daily routine. By mid 1942, mass gassing of Jews using Zyklon-B began at Auschwitz, where extermination was conducted on an industrial scale with 2.5 million persons eventually killed through gassing, starvation, disease, shooting, and burning.

At Auschwitz, so called camp doctors also performed vile and lethal medical experiments on concentration camps inmates, torturing Jewish children, Gypsy children and many others. "Patients" were put into pressure chambers, tested with drugs, castrated, frozen to death, and exposed to various other traumas.

In late 1943, Höss was appointed chief inspector of the concentration camps and worked hard to improve the 'efficiency' of the other extermination centres. He performed his job so well that he was commended in a 1944 SS report that called him 'a true pioneer in this area because of his new ideas and educational methods.'

At the approach of the Red Army in 1945, Höss fled Auschwitz and went into hiding in Germany under the name Franz Lang. He was tracked down by Hanns Alexander, a German Jew who had fled Berlin in the 1930's, and was arrested by the Allied military police in 1946, who handed him over to the Polish authorities. In 1947, Hoss was tried and was sentenced to death. He was returned to Auschwitz to be hanged on a one-person gallows built outside the entrance to the gas chamber.

Before his execution, Höss related how he often felt weak-kneed at having to push hundreds of screaming, pleading children into the gas chambers:

"I did, however, always feel ashamed of this weakness of mine after I talked to Adolf Eichmann. He explained to me that it was especially the children who have to be killed first, because where was the logic in killing a generation of older people and leaving alive a generation of young people who can be possible avengers of their parents and can constitute a new biological cell for the reemerging of this people."

His last words acknowledged his responsibility for all that occurred in Auschwitz and he did not appeal for leniency. He only asked for permission to send a farewell letter to his family and to return his wedding ring to his wife. On the morning of April 16, 1947, several dozen yards from his former villa near Crematorium I in the main camp, Rudolf Höss was hanged.
