PROSSTITZ (Prossnitz ), DANIEL (Steinschneider ; 1759–1846), Hungarian rabbi. Born in Tobitschau near Prossnitz (Prostejov), Daniel studied first in Moravia and later in Pressburg under the rabbi of the town Meir b. Saul *Barby and was later appointed by Meshullam *Igra to his bet din there. Eventually he succeeded Rabbi M. Toska, the head of the bet din. In addition he was appointed rabbi to a society for the study of the Talmud (Ḥevrah Shas) established in Pressburg. He served the Pressburg community in these capacities for 50 years. Prosstitz recommended Moses *Sofer for the vacant position of rabbi of Pressburg and it was largely due to his conduct of the negotiations that Sofer was appointed. Prosstitz also occupied himself with Kabbalah and used to fast frequently, especially after a dream.
He published the Sefer ha-Yashar of Jacob Tam, and left responsa and novellae to the Talmud in manuscript. Responsa addressed to him are found in the Resp. Ḥatam Sofer, in Ezekiel *Landau's Noda bi-Yhudah, and in the responsa of his other great contemporaries.
