WARDER CRESSON came from an evangelical Quaker family. He was convinced that the redemption of the Jewish people was a necessary condition for the Christian Salvation. His friends appealed to Secretary of State, John C. Calhoun, to appoint him U.S. consul in Jerusalem. Cresson set out in 1844, but American officials became aware of Cresson’s controversial character, and the appointment was rescinded by the U.S. government a month later. Cresson continued to represent himself as the American consul and conducted himself with appropriate aplomb. In 1848, he converted to Judaism, changed his name to Michael Boaz Israel, and divorced his wife. Cresson returned to Jerusalem, remarried, and worked to develop agriculture as a way of improving the condition of the Jews. He died in Jerusalem in 1860 and was buried on the Mount of Olives.
