A former assistant professor in Emory University’s German Studies Department has sued the university, claiming that he was denied tenure because he is Jewish.

H. Erik Butler sued Emory after the U.S. Equal Employment Opportunity Commission found reasonable cause last year to conclude that Butler was discriminated against by his German-born department chairman because of his religion, according to the complaint. Emory removed the suit, originally filed in DeKalb County last month, to U.S. District Court on Jan. 13.
