Paulus Stephanus Cassel

Paulus Stephanus Cassel (February 27, 1821 – December 23, 1892), born Selig Cassel, was a German Jewish convert to Christianity, writer, orator, and missionary to Jews.

Cassel was born in Gross-Glogau, Silesia, Prussia. His father was a sculptor, and his brother David was a well-known rabbi in Berlin and docent at the Hochschule für die Wissenschaft des Judenthums (College for the Study of Judaism). Cassel studied at the Gymnasium of Glogau and Schweidnitz and at the University of Berlin, where he followed with special interest the lectures of the historian Leopold von Ranke. In 1849 he edited in Erfurt Constitutionelle Zeitung, and in 1850-56 Erfurter Zeitung, in a royalist spirit. He later received a doctor of divinity degree from Vienna.

According to his own statement, his Christian friends, and especially his study of the history of Israel, led him to Christianity. He was baptized as a member of Evangelical Church in Prussia on May 28, 1855 in the St. Peter's Church of Büßleben (now a locality of Erfurt), receiving the name "Paulus Stephanus." In later years he celebrated May 28 as his "second birthday". He became librarian of the Royal Library in Erfurt and secretary of the Academy in Erfurt in the following year. He remained in Erfurt till 1859. King Frederick William IV bestowed the title of professor on Cassel in recognition of his loyal labors. In 1860 he removed to Berlin, where he was a teacher at a gymnasium for a short time, and occupied himself with literary work. He was briefly editor of the official Deutsche Reform. He delivered public lectures, which drew increasingly large audiences, both Jews and Gentiles. These lectures made him known throughout Berlin and the country.
