In 1926 Siegfried Jacobsohn, founder and editor of Die Weltbühne [The World Stage], offered Ossietzky a position on his editorial staff. Jacobsohn had already become involved in efforts to uncover and publicize the secret rearmament of Germany, and Carl von Ossietzky was to continue this unpopular editorial policy, for Jacobsohn died unexpectedly in December, 1926, and shortly thereafter his widow named Ossietzky editor-in-chief. In March, 1927, Die Weltbühne published an article by Berthold Jacob3 which criticized the Reichswehr for condoning paramilitary organizations. Ossietzky, as the editor responsible, was tried for libel, found guilty, and sentenced to one month in prison.
