Adolf Hitler's bodyguard
When Hitler returned to Munich from military service in 1918, he became a member of the Nazi Party, an extremist far-right political party in Bavaria. In 1921, he was elected leader of the party. As his speeches promoted violence and racism, Hitler needed permanent security.
Hermann Röchling
Röchling met Adolf Hitler in 1933 and promoted formation of the "German Front" in the Saar at Hitler's suggestion.
After the expiry of the League of Nations mandate over the Saar in 1935, Hermann Röchling committed himself to the return of Saarland to Germany.
Röchling was violently antisemitic, and when the Nazis temporarily reduced their attacks on Jews before the January 1935 plebiscite on the return he protested that the Saar risked turning into a "Jewish nature reserve".
Röchling joined the Nazi Party in 1935.
In 1935 he was appointed to the Reich's Armament Advisory Board (Rustungsbeirat).
Hermann Röchling was a confidant of Hitler, who valued his knowledge of industry. 
Röchling wrote several memoranda for Hitler.
In his "Thoughts on the Preparation for the War and Its Implementation" in August 1936 he urged Hitler to declare war on the Soviet Union.
