Solomon Bennett Freehof (August 8, 1892 – 1990) was a prominent Reform rabbi, posek, and scholar. Rabbi Freehof served as president of the Central Conference of American Rabbis and the World Union for Progressive Judaism. Beginning in 1955, he led the CCAR's work on Jewish law through its responsa committee. He also spearheaded changes to Reform liturgy with revisions to the Union Prayer Book (siddur). For many years, he served as the pulpit rabbi at Rodef Shalom in Pittsburgh, PA ). According to the congregation, "For more than 35 years, Dr. Freehof's weekly book review series attracted audiences of more than 1,500 Christians and Jews."
Freehof was born in London, moved to the U.S. in 1903, received a degree from the University of Cincinnati (1914) and ordained from Hebrew Union College (1915). He was a World War I army chaplain, a liturgy professor at HUC, and a rabbi at Chicago's Congregation Kehillath Anshe Maarav before moving to Pittsburgh. He retired in 1966.
