Samuel Hirsch, (June 8, 1815 – May 14, 1889) was a major Reform Judaism philosopher and rabbi who mainly worked and resided in present-day Germany in his earlier years.Having received a call from the Reform Congregation Keneseth Israel, Philadelphia, Pennsylvania, in 1866, he resigned his post in Europe and moved to the United States.During his rabbinate in Philadelphia Hirsch organized the Orphans' Guardian Society, and was the founder of the first branch in the United States of the Alliance Israélite Universelle.His "Katechismus der Israelitischen Religion" was also constructed on original lines; he considered the Biblical legends to be psychological and typical allegories, and the ceremonies of Judaism to be symbols of underlying ideas.He denied that Judaism is a law; it is Lehre ("teaching" or "lore") but is expressed in symbolic ceremonies that may be changed in accordance with historic development.
