Liberat Weiß was an 18th-century German Franciscan priest and missionary who served the Catholic Church. Born in Konnersreuth in 1675, he joined the Order of Friars Minor in Graz, where he adopted his religious name. After training in Rome, he undertook difficult missionary journeys to Ethiopia via the Nile. He eventually reached Gondar alongside two companions, but their efforts were met with intense opposition from the local ruler. Following his refusal to renounce his theological convictions, he was martyred in 1716.
