Guðmundur Guðmundsson was one of Iceland's first converts and missionaries. Born in Oddi, Iceland, he traveled to Copenhagen to work as a goldsmith and joined the LDS Church there in 1851. He returned to Iceland that year to preach the gospel, but his family was unreceptive, and his preaching resulted in public persecution and government orders to cease. He stayed in Iceland until 1854, when he began a mission in Denmark for eighteen months. While there, he was imprisoned for preaching for seven weeks. He was then conscripted into the Danish army for four years, but after a year he was released because of poor health. He migrated to Utah, married, and lived in various settlements. For a time he associated with the Morrisite sect but later returned to fellowship with the church headed by Brigham Young.
