After receiving a traditional upper-class education he went to fight at the front as an officer with the 6th Royal Saxon Infantry Regiment in the First World War.

From 1923 to 1926 von Tschammer became the leader in Saxony of the Young German Order, one of the largest paramilitary groups in the Weimar Republic.

He replaced the DRA with a Nazi-oriented organization, the Deutscher Reichsbund für Leibesübungen (DRL) on 27 July 1934, to serve as the official sports governing body of Nazi Germany.

This lavishly illustrated work had many pictures and information about the various Nazi organizations, i.e. SA, NSKK, Bund Deutscher Mädel, Hitler Jugend, etc.

This was in line with the ideals of Friedrich Ludwig Jahn, the "Father of physical exercises", who connected the steeling of one's own body to a healthy spirit and promoted the idea of a unified, strong Germany.

[7] Under von Tschammer's leadership, German Jewish athletes were systematically hindered by being denied adequate facilities and the opportunity to compete.

[8] Hans von Tschammer und Osten enjoyed the Nazi sports festivals in which he took a keen interest as organizer.

He played a major role in the structure and organization of the Olympic Games together with Carl Diem, who was the former secretary of the Deutscher Reichsausschuss für Leibesübungen (DRA).

In January 1937, he was made head of the Sports and Physical Exercise Department in the Reich Ministry of the Interior and, in 1938, he was given the rank of State Secretary there.

Von Tschammer would never see the end of the organization he had led for so long, nor Germany's defeat in World War II, for he died from pneumonia in Berlin in 1943.
