ISAACS, Samuel Myer, clergyman, born in Leeuwarden, Holland, 4 January, 1804; died in New York city, 19 May, 1878. He went to London with his family in 1814, was called to the pastorate of a New York synagogue in 1839, and, on a division in the congregation in 1845, a new body was organized, of which he was minister until his death. Mr. Isaacs was successful in arousing his community to philanthropic work, and he was among the first to labor for the establishment of Jewish institutions in New York, like the Mount Sinai hospital, the Hebrew free schools, and the United Hebrew charities. He was a popular speaker, and was often called to consecrate synagogues throughout the country, and was a frequent orator at public assemblies. In 1857 he established the "Jewish Messenger," as an organ of conservative Judaism, and advocated his views with warmth and ability. He was a life-long friend and correspondent of 'Sir Moses Montefiore. A brief biography of him was published by his sons on the twenty-fifth anniversary of the "Jewish Messenger" in January, 1882.
