Gemma La Guardia Gluck (24 April 1881 – 1 November 1962) was an American writer, of Italian Jewish origin, who lived in Hungary and was a survivor of the Holocaust. Her autobiography, published in 1961, tells of her experience as a survivor of the Ravensbrück concentration camp, but also offers vivid memories of her childhood spent in America with her parents and brother Fiorello La Guardia, the future first Italian-American mayor of New York.
