Tehilla Lichtenstein (1893 – 1973) was a cofounder and leader of Jewish Science, as well as an author. She was born in Jerusalem and immigrated to America when she was eleven years old. Her parents were Hava (Cohen) and Rabbi Haim Hirshenson. She earned a B.A. degree in Classics from Hunter College and an M.A. degree in literature from Columbia University.
Tehilla originally ran the religious school of the Society of Jewish Science in New York, where she also taught Hebrew and Bible. She became the spiritual leader of the Society of Jewish Science when her husband Morris, who had been its leader, died in 1938. Morris's will had declared that the position should go to one of their sons, or to Tehilla if neither of their sons was willing, which as it turned out they were not. Thus Tehilla became the first Jewish American woman to serve as the spiritual leader of an ongoing Jewish congregation. On December 4, 1938, Tehilla gave her first sermon as the new leader of the Society of Jewish Science. It was entitled “The Power of Thought.”  According to the New York Times, which gave a brief notice to the event, over five hundred people attended this sermon. She continued to preach from the pulpit until 1972. She gave over five hundred sermons in all.
