Theodor Dannecker (27 March 1913 in Tübingen – 10 December 1945 in Bad Tölz) was an SS Hauptsturmführer (captain) and one of Adolf Eichmann's associates. As a Judenberater, he was one of those who orchestrated the Final Solution in several countries during the Holocaust.
After completing trade school, Dannecker first worked as a textile dealer, until he became a member of the Nazi Party and the SS in 1932.
In 1934, Dannecker became a member of the SS-Verfügungstruppe, a special combat support force, and a year later in 1935, he also became a member of the Sicherheitsdienst (SD) (SD, Security Service was primarily the intelligence service of the SS and the Nazi Party in Nazi Germany). In March 1937 came Dannecker's transfer to the Judenreferat (Department of Jewish Affairs) in the SD's main office. From September 1940 until July 1942, Dannecker was leader of the Judenreferat at the SD post in Paris, where he ordered and oversaw round ups by French Police. More than 13,000 Jews were deported to Auschwitz concentration camp where most died in the Final Solution.
Owing to misuse of his position, partially due to his theft of German confiscated property, he was ordered back to Berlin in August 1942. From January 1943 Dannecker was the highest German official in charge of the Final Solution, in all the Bulgarian territories. During March 1943, 11,343 Jews were deported from the German occupied Bulgarian annexed territories of Greece and Yugoslavia to Auschwitz and Treblinka. Only 12 survived.
