The author, R. Eliezer David Grünwald, Av Beit Din of Satmar (ca. 1866-1928), prominent Torah leader and yeshiva dean in Hungary and Transylvania. Close disciple of his brother R. Moshe Grünwald, the Arugat HaBosem. He studied for a short period under R. Shmuel Ehrenfeld, author of Chatan Sofer. He served as rabbi and dayan in many prominent communities – Bardejov, Dunajská Streda, Tzelem (Deutschkreutz) and Vişeu de Sus – establishing in each place a large yeshiva where he edified many disciples, including dozens of rabbis and poskim. His yeshiva in Vişeu de Sus alone had hundreds of students. In 1921, he was chosen as Av Beit Din of Satmar, and he headed one of the largest yeshivas of Hungary, the very largest in Transylvania. After his passing, his disciples began to publish his novellae, from which they printed Responsa Keren LeDavid on Orach Chaim (Satmar, 1929; other parts of the work were lost in the Holocaust), Keren LeDavid on the Torah (Satmar, 1930-1939), Keren LeDavid – Homilies (Satmar, 1934), and more.
