Halbe was born at the manor of Güttland near Danzig, where he grew up. He was a member of an old family of peasants who had immigrated two centuries earlier from Westphalia. He attended the gymnasium at Marienburg. In 1883 he began his study of law at the University of Heidelberg. He studied history and Germanic philology at the University of Berlin, 1885-1887. He obtained his doctorate at the University of Munich in 1888. He then moved to Berlin. In both Berlin and Munich, Halbe became acquainted with the leaders of the new naturalistic movement in German literature, and became associated with the Free Stage movement in 1889. He was strongly influenced by the association with, and the works of, Johannes Schlaf and Arno Holt. In the spring of 1890, he wrote the playFree Love, later called Ein Verhältnis. He married the same year. Halbe was not entirely in accord with the Freie Bühne, and with consistent naturalism, as the latter deviated considerably from his own tendencies. He published Eisgang in 1892, and then his primary work, Jugend, in 1893, which was, after Hauptmann's Die Weber, the most successful contemporary stage play in Germany. It was difficult for him to get Eisgang and Jugend performed, although Jugend got a performance on the Freie Volksbühne in 1892. Jugend was especially difficult to place: famous theatre managers in Berlin refused it, but Lautenburg accepted and performed it with great success in 1893. The drama, whose unaffected and sympathetic treatment of sexual relationships made no concessions to prevailing bourgeois morality, won it the enthusiastic praise of socialist critics. Franz Mehring, the principal spokesman of the Social Democratic Party of Germany on culture, warmly welcomed Jugend and referred to Halbe, along with Gerhardt Hauptmann, as "one of the princes of Genius land." In 1917 an operatic version of Jugend, composed by Ignatz Waghalter, was premiered in Berlin at the Deutsches Opernhaus to great acclaim. Halbe's next play, the comedyThe Touristin America made the impression of being witless, and his reputation rapidly declined. Constant laments were uttered by critics as to his failure to fulfill the promise of his early work. Halbe decided to move to the rural atmosphere of Kreuzlingen, on Lake Constance, in 1894. In 1895 Halbe went to Munich again, where, with Josef Ruederer, he founded the Intimate Theater for Dramatic Experiments, in which writers and poets appeared on the stage, and was a co-founder of Munich Popular Theatre. As a member of the Munich artist society, his circle included Otto Erich Hartleben, Frank Wedekind, Hanns von Gumppenberg, Ludwig Thoma and Eduard von Keyserling. He began writing again. The dramas Lebenswende and Mutter Erde and the novelle Frau Mesek are of this period. When the National Socialists seized power in January 1933, Halbe, like Gerhart Hauptmann, did not openly speak against them, and held aloof from politics. But on 22 October 1933, he signed a statement of loyalty to Adolf Hitler. As one of the few writers of significance that remained in Germany, the Nazis used him for advertising, which after the war damaged his reputation, and led to widespread rejection of his work. In 1933 and 1935 his biography Scholle und Schicksal and Jahrhundertwende were published. Halbe died in the age of 79 at his manor house in Neuötting, Bavaria.
