Tibor Hirth was a priest in the Diocese of Vác. He was likely born on March 18, 1922, in Újpest. In 1948, he served as an assistant pastor in Lajosmizse, and from 1949 to 1950, he served as a parish priest in Hernád. During the communist persecution of the Church in 1950, he was subjected to harassment by the ÁVH. A memoir written by Miklós Furiakovics lists the priests with whom he was imprisoned in the Vác prison and the Kozma Street detention center, and Hirth is among them.
He later emigrated to the United States, where he served in the Hungarian Catholic community in Schenectady, New York. According to some sources, he later left the priesthood and started a family.
