German war criminal, an SA officer and SS senior leader, best known as the commander of the Tilsit task force, which murdered several thousand Jews in Lithuania in the summer of 1941 in Klaipeda.
Shortly after the National Socialists (Nazis) came to power in the Spring of 1933, Fischer-Schweder was accepted into the police force. On 26 June 1933, Fischer-Schweder, together with his then mentor Karl Belding, murdered the former SA officer Helmuth Unger, who was considered a traitor after it became known that he acted as an informer for the police of the Weimar Republic.
In May 1934, Fischer-Schweder was transferred to Breslau as a detective commissioner. In the meantime he was accused by the Berlin SS of having participated in the alleged Schorfheide assassination attempt on Heinrich Himmler together with Belding on 19 June 1934, which, however, probably never happened. Himmler was firmly convinced that Belding and Fischer-Schweder were responsible for the assassination attempt, together with Belding, and on 30 June 1934 in the course of the Röhm affair they were arrested under Himmler’s orders by the SS in Breslau. Both men were taken into custody by the SS at the police headquarters in Wroclaw, and were detained as prisoners. While Belding was taken out of his cell by SS members, along with six other SA members from Wroclaw, on the night of 1 July, and taken to a wooded area outside of Wroclaw and shot, Fischer-Schweder escaped this fate by luck, since an SS man spoke up for him. A few weeks later, he was released.
Schweder returned to the police service, working in the Silesian region (Breslau and Liegnitz) until the outbreak of World War II. He was appointed acting police director of Memel in October 1940. In January 1941, he was confirmed in this position and appointed permanent Memel police director. He was transferred to the SS on 16 August 1941 with the approval of Himmler.
In Memel in the Summer of 1941, Fischer-Schweder was involved in the formation of the Tilsit task force formed on the occasion of the German invasion of the Soviet Union. This command carried out mass executions in the area of ??Lithuania during the first months of the Russian campaign.
After World War II, Fischer-Schweder hid under the name Bernd Fischer. Under his new identity, he initially worked as a sales representative for a vacuum cleaner company in Stuttgart before trying to get back into the public service.
In 1955 Fischer-Schweder became head of the Wilhelmsburg refugee camp near Ulm. However, his past became known and he was dismissed from service. He was arrested and at the Ulm Einsatzgruppen trial in 1958, Fischer-Schweder was sentenced on 29 August 1958 to 10 years in prison for aiding and abetting murder in 526 cases. Fischer-Schweder died of a pulmonary embolism on 28 November 1960 in the Hohenasperg prison near Ludwigsburg at age 56.
