Walter (Walther) Rauff (19 June 1906 – 14 May 1984) was a mid-ranking SS commander in Nazi Germany. From January 1938, he was an aide of Reinhard Heydrich firstly in the Security Service (Sicherheitsdienst or SD), later in the Reich Security Main Office. He worked for the Federal Intelligence Service of West Germany (Bundesnachrichtendienst) between 1958 and 1962, and was subsequently employed by the Mossad, the Israeli secret service. His funeral in Santiago, Chile, was attended by several former Nazis. Rauff is thought to have been responsible for nearly 100,000 deaths during World War II. He was instrumental in the implementation of the Nazis' genocide by mobile gas chamber. His victims included Communists, Jews, Roma and people with disabilities. He was arrested in 1945, but subsequently escaped and was never brought to trial. In the late 1970s and the 1980s, he was arguably the most wanted Nazi fugitive still alive. From the Navy to the SS According to the MI5 file on Walter Rauff released in 2005: Rauff joined the Kriegsmarine (the German Navy) in 1924 as a young cadet. After a period of training as a midshipman he was promoted to Lieutenant in 1936 and given command of a minesweeper. He was a friend of Reinhard Heydrich, who also served in the Navy in the 1920s. Heydrich was hired by SS chief Heinrich Himmler in 1931 to serve as the head of the SS counter-intelligence system, and when Rauff resigned from the Navy in 1937, Heydrich took him under his wing. Rauff was given the job of putting the SS and its security service, the Sicherheitsdienst, onto a war footing. During his thirteen years in the Navy, Rauff became acquainted with Reinhard Heydrich and saw service in South America and Spain as a young officer in 1924. In 1937, Rauff left the Navy following an adultery scandal, but he was discharged "with all honours", as he said in a 1972 deposition before a German prosecutor in Santiago de Chile. Between 1940 and 1941, Rauff returned to the Navy as a volunteer, commanding a mine sweeper flotilla in the English Channel. He was promoted to Lieutenant Commander (Korvettenkapitän) in April 1941, shortly before he was discharged from active service, he then returned to the Reich Security Main Office. During early 1940, he headed the SD in German-occupied Norway for few months. Gas van engineering In 1941 and 1942, Rauff was
