active in 1913. He was also extremely critical regarding the stage efforts of expressionist writers. However, he made an exception for Georg Kaiser and Ernst Toller both of whom he esteemed highly. During the Weimar Republic, Jacobsohn belonged to the few critics who immediately saw the potential of Bertolt Brecht, Arnolt Bronnen and Carl Zuckmayer even though he was already plagued by theatre fatigue. Jacobsohn also expanded the horizon of the criticism of his magazine by taking on new art forms such as film. He managed to obtain the collaboration of film critics such as Hans Siemsen, Frank Warschauer, Roland Schacht and Rudolf Arnhe. Even in music criticism he managed to put forward new accents by employing the Social-Democrat Wagnerian Klaus Pringsheim Sr. even though Jacobsohn was a resolutely opposed to Wagner. Towards the end of World War I, Jacobsohn became politically closer to the socialist USPD.

Jacobsohn replied in 1924 that Tucholsky should lay off Ebert since, under his successor, he would be yearning for the return of Ebert. He also remarked that Ebert had succeeded in the dissolution of the Reichstag which meant that he would be with Tucholsky for some time yet and be able to pay his salary whereas under a new government Tucholsky would have to look for him and his money in a mass grave. Jacobsohn had an extremely pugnacious personality. In the answer column of his magazine as well as in articles and serials he attacked opponents of whom one would expect they were deserving of his support. In 1913 a bitter conflict erupted with Theodor Lessing. Jacobsohn had printed Lessing's review of Hermann Sudermann's play Der gute Ruf whereupon Sudermann went to
