Vilmos Vázsonyi (born as Vilmos Weiszfeld; 1868–1926) was a Hungarian publicist and politician of Jewish heritage. Vázsonyi was born at Sümeg. He was educated at Budapest, where his remarkable eloquence made him the leader of all student movements during his university career. After he had completed his studies, the most vital social questions found in him an earnest investigator. He aroused a national sentiment against dueling, his success being proved by the numerous anti-dueling clubs in Hungary. Later, he began a social and journalistic agitation on behalf of the official recognition of the Jewish religion, and kept the matter before the public until the law granting recognition was sanctioned in 1895.
