Born in
Connellsville,
Pennsylvania,
United States into an Orthodox Jewish family. His parents, Aaron and Jennie Rader Marcus, were immigrants from Vidz, Lithuania. Marcus became interested in Reform Judaism at the age of 15. At that time, he traveled to
Hebrew Union College (HUC), in
Cincinnati,
Ohio, to begin his rabbinical training. After a two-year interim during
World War I, when he served in the American military, Marcus returned to graduate studies in Cincinnati. After receiving rabbinical ordination in 1920, Marcus was appointed to the faculty of HUC, where he began teaching biblical history. In 1922, Marcus traveled to
Berlin to study Jewish history with
Ismar Elbogen, who awarded Marcus a
Ph.D. in 1925. In that year, Marcus married Antoinette Brody in
Paris. The couple had one daughter, Merle, who was born in 1929. After briefly studying at
Hebrew University in
Jerusalem in 1926, Marcus returned to Cincinnati, where he lectured at HUC consistently until 1995. In 1959, he was named the
Adolph S. Ochs Professor of American Jewish History. In 1965, he was appointed to HUC's
Milton and Hattie Kutz Distinguished Service Chair in American Jewish History. Marcus devoted most of his post-
World War II historical career to American Jewish history and founded the American Jewish Archives in Cincinnati in 1947 on the campus of HUC. Although he is considered to be the first trained historian of the Jewish people born in America, he is, perhaps, best known for his work on Medieval European Jewish history,
The Jew in the Medieval World: A Source Book: 315-1791, first published in 1938. In the 1970s, while director of the American Jewish Archives, Marcus publicly shared the account of
Regina Jonas in response to the ordination of Rabbi
Sally Priesand in 1972. Marcus informed
The American Israelite in July 1973 that the only other known Jewish woman to receive ordination was Regina Jonas of Berlin but that she perished at the hands of the Nazi regime. Marcus also provided the title of Jonas' thesis, "Can a Woman Become a Rabbi?". In 1949, he was elected president of the
Central Conference of American Rabbis (CCAR), a position he served in until 1951. Marcus died on the eve of November 14, 1995, at the age of 99. Marcus was the mentor of
Jonathan Sarna. ==Works==
