Austrian author and communal worker; born in Kremsier Jan. 15, 1828. In his youth he frequented various yeshibot, acquiring secular learning in private; and in 1848 he went to Vienna, where he devoted himself to commercial life, at the same time attending lectures at the university. Baumgarten was elected to the Sechshaus municipal board in 1861, being one of the first Jews in Austria to be elected to such an office; he was made warden of the temple of Vienna in 1870; and was in 1872 elected a member of the board of the Jewish congregation of that city, in which capacity he displayed a great and beneficent activity. A prominent part was taken by him in the foundation of the Bet ha-Midrash in Vienna, in which such men as Isaac H. Weiss and M. Friedmann found an opportunity to develop their talents; and he was one of the founders of the Israelitische Allianz and represented the congregation in the state's boards of education. The emperor honored him by granting him an order of merit; and on the occasion of his seventieth birthday he was the recipient of enthusiastic ovations.
