Founder of the Latter Day Saint movement (1805–1844)
Joseph Smith Jr. (December 23, 1805 – June 27, 1844) was an American religious leader and the founder of Mormonism and the Latter Day Saint movement. Publishing the Book of Mormon at the age of 24, Smith attracted tens of thousands of followers by the time of his death fourteen years later. The religion he founded is followed to the present day by millions of global adherents and several churches, the largest of which is the Church of Jesus Christ of Latter-day Saints (LDS Church).
