Rabbi Solomon B. Freehof, PhD (z"l) (1892 1990) was born in London to a family that traced its roots to Schneur Zalman of Liadi, the founder of Lubavitch Hasidism (CHaBaD). Upon moving to the United States, he attended Hebrew Union College after which he rose to become a world-renowned authority on Jewish law, a prolific writer of responsa for Reform Jews, a prolific author and prayer-book editor, and a pulpit rabbi for much of his life at Rodef Shalom Temple of Pittsburgh.
