La Guardia was the city's first Italian-American mayor, but was not a typical Italian New Yorker. He was a Republican Episcopalian who had grown up in Arizona and had a Triestine Jewish mother and a lapsed Catholic father. He spoke several languages; when working at Ellis Island, he was certified as an interpreter for Italian, German, Yiddish, and Croatian. It served him well during a contentious congressional campaign in 1922. When Henry Frank, a Jewish opponent, accused him of anti-Semitism, La Guardia rejected the suggestion that he publicly disclose that his mother was Jewish as "self-serving". Instead, La Guardia dictated an open letter in Yiddish that was also printed in Yiddish. In it, he challenged Frank to publicly and openly debate the issues of the campaign entirely in the Yiddish language. Frank, although he was Jewish, could not speak the language and was forced to decline—and lost the election.
