German author; born at Berlin Oct. 20, 1861. Educated in the German capital, where he still resides, he became well known through his political and social articles in the "Nation," "Frankfurter Zeitung," and especially in the "Gegenwart," written over the nom de plume of "Apostata"; they were collected and published under that name in Berlin in 1892. In the same year he founded the "Zukunft," one of the leading German journals, which he is still (1903) editing. He was recently arrested and imprisoned by the government under the charge of lese-majesty. Harden embraced Christianity when a mere boy. His original name was Witkowski (see his "Zukunft," Oct., 1903).
