Dr. Erich Schmidt-Leichner (October 14, 1910–March 17, 1983) was a German lawyer who made a name as a distinguished defense counsel at the Nuremberg Trials. In 1978, he was a defense counsel in the Klingenberg Case, where a married couple were accused of negligent homicide for failing to call a medical doctor during an exorcism of their daughter. In this case, Schmidt-Leichner unsuccessfully claimed that exorcism was legal as the German constitution protects citizens in the unrestricted exercise of their religious beliefs.
