Lehmann was born on 28 November 1864, in
Zürich. In Zürich he first went to the private school ''Beust'sche Privatschule'' and then to the
gymnasium. In 1900, Lehmann left Switzerland and moved to Germany, where he bought the medical journal "
Münchener Medizinische Wochenschrift" (i.e. "Munich Medical Weekly Magazine"), which he soon managed to make the most widely circulated journal of its kind in Germany. Many of the articles dealt with subjects that were to shape national-socialist ideology, like compulsory sterilization. Lehmann became a member of the
Fatherland Party in 1917. He also became a member of the
Thule Society. He established the
Deutsche Volksverlag, which he handed over to
Ernst Boepple. Lehmann also published the journal
Deutschlands Erneuerung (Germany's Renewal), which was edited by the
Pan-German League. Lehmann's publishing house was an important connection between the
German Nationalist Protection and Defiance Federation, the
Marinebrigade Ehrhardt, then the
Organisation Consul and the
German National People's Party. In 1923, Lehmann took part in the
Beer Hall Putsch. He joined the
Militant League for German Culture in 1928, and became a member of the
NSDAP in 1931. In 1934, at his 70th birthday, he received many honors, including the
Eagle Shield of the German Reich. He died on 24 March 1935 in
Munich. ==Works==
