Thomas S. Monson, 16th president of the Church of Jesus Christ of Latter-day Saints, died Tuesday night at his home in Salt Lake City, at age 90. Monson was president, "prophet, seer, and revelator" of the Mormon church for nearly a decade, but he had been one of the church's 12 apostles since 1963. He was part of the Mormon church's top ranks during a period of large expansion and significant change, including the decision to allow black Mormons to become full members of the church. Monson's presidency also covered tumult in the Mormon church, including a push against same-sex marriage and severance of the LDS relationship with the Boy Scouts. He will be succeeded by Russell M. Nelson, 93.
