The Society of Jesus is a Christian male religious congregation of the Catholic Church. The members are called Jesuits. In 1888, a Jesuit mission was established on Nelson Island and a year later moved to Akulurak ("Akuluraq", the former site of St. Mary's Mission) at the mouth of the Yukon River. Segundo Llorente (1906–1989) was a Spanish Jesuit, philosopher and author who spent 40 years as a missionary among the Yup'ik people in the most remote parts of Alaska. His first mission was at Akulurak.
