Otto Strasser

Otto Johann Maximilian Strasser (also , see ß; 10 September 1897 – 27 August 1974) was a German politician and an early member of the Nazi Party. Otto Strasser, together with his brother Gregor Strasser, was a leading member of the party's more radical wing, whose ideology became known as Strasserism, and broke from the party due to disputes with the dominant Hitlerite faction. He formed the Black Front, a group intended to split the Nazi Party and take it from the grasp of Hitler. During his exile and World War II, this group also functioned as a secret opposition group.

Historian Hans Mommsen has commented that Otto Strasser was "in most respects" the intellectual superior of his brother Gregor. Provided by Wikipedia
