The Gestapo (Secret State Police) was the official secret police of Nazi Germany and German-occupied Europe.

He was imprisoned from 1948 to 1973. On 6 April 1950 he was convicted of murdering 55 Jews from 1938 to 1943 and the attempted murders of 21 Jews, as well as for maltreatment of 29 Jewish prisoners in Frankfurt. His trial was five weeks long, with 157 witnesses testifying, including some of his victims. Heinrich Baab sent many of Frankfurt's Jews to camps from the rail station. Baab's supervisor at the Lindenstrasse station was Oswald Poche. Before joining the police in 1928 in Stettin, Baab was a locksmith.

In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–45), it grew from a small paramilitary formation to one of the most powerful organizations in Nazi Germany.

Document 10: Sturm-Zigaretten: Sturm-Zigaretten (Storm Cigarettes or Assault Cigarettes) was a brand of cigarettes sold to generate funds for the Nazi Party's Sturmabteilung (SA).

The Sturm cigarette factory produced four brands in total: Trommler, Alarm, Sturm and Neue Front. Through this scheme, a typical SA unit earned hundreds of Reichsmarks each month. There is evidence that coercion was used to promote the sale of these cigarettes. SA members were expected to smoke Sturm cigarettes exclusively. The brand was also used to make the prospect of serving in the German army more appealing, with sets of cards being produced which depicted attractive army uniforms from history. The SA stopped manufacturing cigarettes in 1934.
