Józef Innocenty Guz was a Polish Conventual Franciscan priest who lived from 1890 to 1940. Born in Lviv, he joined his religious order in 1908 and received holy orders in 1914. Throughout his ministry, he served various Polish parishes and worked alongside Maximilian Kolbe. After being arrested by Soviet authorities in 1940, he managed to escape their custody, only to be captured by the Gestapo. He was eventually killed by a guard at the Sachsenhausen concentration camp, where he died as a martyr.
