Mormonism is the predominant religious tradition of the Latter Day Saint movement of Restorationist Christianity started by Joseph Smith in Western New York in the 1820s and 30s. After Smith was killed in 1844, most Mormons followed Brigham Young on his westward journey to the area that became the Utah Territory, calling themselves The Church of Jesus Christ of Latter-day Saints (LDS Church)
James Edward Talmage (21 September 1862 – 27 July 1933) was an English chemist, geologist, and religious leader who served as a member of the Quorum of the Twelve Apostles of The Church of Jesus Christ of Latter-day Saints (LDS Church) from 1911 until his death.
