Rabbi Isaac Mayer Wise (1819-1900) was the leading organizational genius behind the rise of American Reform Judaism in the late 19th century. He played a central role in the founding of three major Reform Jewish institutions that still exist today: The Union of American Hebrew Congregations [1873], now the Union for Reform Judaism, the parent body of Reform synagogues; the Hebrew Union College [1875], the Reform movement's rabbinical seminary; and the Central Conference of American Rabbis [1889], the Reform rabbinical association.
