Willibrord was an Anglo-Saxon monk and missionary who lived from approximately 658 to 739. Born in the Kingdom of Northumbria, he studied in Ireland before being sent to convert the pagan Frisians. He is recognized as the first Bishop of Utrecht and is frequently called the Apostle to the Frisians. After traveling to Rome to receive official papal authorization for his mission, he established several religious foundations, including the Abbey of Echternach. He died in Luxembourg at the age of 81.
