George Paloczi-Horvath (1908–1973) was a Hungarian writer, best known for his 1959 autobiography book The Undefeated. He was born in 1908 to a privileged Hungarian family. As a young journalist, he reported on the rise of fascism in Europe and became a dedicated anti-Nazi. When the German army marched through Budapest in 1941, he fled the country under an assumed name, ending up first in Cairo and, after the war, in London. He returned to Budapest in February 1947, where he edited a magazine and joined the Communist Party. But he was soon arrested as a spy, and spent the next five years in prison. He was subjected to solitary confinement and torture. He was finally released in 1954, and after the Hungarian Uprising in 1956, he left the country for good.
