Rabbi Rava was a Polish librarian living in Prague. He immigrated to the United States and lived in Brooklyn during the Depression era. Rabbi Rava had translated a copy of a mystical text known as the Sefer Yetzirah and used it in the creation of a golem in 1932. Along with his friend Alice Cohen, Rava sent the golem to avenge the death of Alice's lover Peter. Rava himself was later murdered by gangsters. He was buried in the Journey's End Cemetery in Brooklyn.
