Carl Schneider

Carl Schneider (December 19, 1891 in Gembitz, Kreis Mogilno, Province of Posen – December 11, 1946 in Frankfurt), professor at Heidelberg University, (1933–1945) chairman of its department of Psychiatry,

Schneider joined the Nazi Party in 1932. He defined and elaborated the psychological assumptions of Nazi ideology and science. He coined the term national therapy for ethnic cleansing: ridding the populace of genetic and blood contaminants threatening the psychological and physical health of the German/Aryan population. He collected the brains of murdered Jews, mentally handicapped children, and other victims, for research in his clinic and for instruction. He taught a technique of replacing spinal fluid with air, to get clearer x-rays of the brain.

Schneider, along with Konrad Zucker, helped Heidelberg become one of the two leading training centres for the killing of children for theoretically scientific purposes, which went on at thirty clinics for three years.

After the war; arrest and suicide

At the end of the war, Schneider flew out of Heidelberg on the 29 March 1945. The U.S. occupation authorities barred his reinstatement to the university's medical faculty, even before they learned of his role in the euthanasia program.

Later Schneider was arrested and moved to the internment camp at Moosburg an der Isar. On 29 November 1946, Schneider was given to the German justice authorities in Frankfurt am Main, to be a witness in the trial against Werner Heyde. Prosecutors allegedly told Schneider that in a trial his position would be very bad.

On 11 December 1946, Schneider hanged himself in his prison cell awaiting trial in Frankfurt am Main. His co-workers were not punished and could continue their work. His membership in the Heidelberg academy of sciences was deleted.
