Rabbi Louis Jacobs (1920-2006) was one of the most significant leaders of British Jewry in the 20th century. July 17 marks the 100th anniversary of his birth. To mark this occasion, I had a conversation with Rabbi Elliot Cosgrove, spiritual leader of Park Avenue Synagogue in New York, who wrote his doctoral dissertation on Rabbi Jacobs.
