SALT LAKE CITY (AP) — For more than 50 years, Thomas S. Monson served in top leadership councils for the Mormon church — making him a well-known face and personality to multiple generations of Mormons.

A church bishop at the age of 22, the Salt Lake City native became the youngest church apostle ever in 1963 at the age of 36. He served as a counselor for three church presidents before assuming the role of the top leader of The Church of Jesus Christ of Latter-day Saints in February 2008.

Tuesday night, 90-year-old Monson died at his home in Salt Lake City, according to church spokesman Eric Hawkins.

As president of the nearly 16-million member faith, Monson was considered a prophet who led the church through revelation from God in collaboration with two top counselors and members of the Quorum of the Twelve Apostles.

The next president was not immediately named, but the job is expected to go to the next longest-tenured member of the church's governing Quorum of the Twelve Apostles, Russell M. Nelson, per church protocol.

Monson's presidency was marked by his noticeably low profile during a time of intense publicity for the church, including the 2008 and 2012 campaigns of Mormon Mitt Romney for President. Monson's most public acts were appearances at church conferences and devotionals as well as dedications of church temples.

Monson will also be remembered for his emphasis on humanitarian work; leading the faith's involvement in the passage of gay marriage ban in California in 2008; continuing the church's push to be more transparent about its past; and lowering the minimum age for missionaries.

Mormons considered Monson a warm, caring, endearing and approachable leader, said Patrick Mason, associate professor of religion at Claremont Graduate University in California. He was known for dropping everything to make hospital visits to people in need. His speeches at the faith's twice-yearly conferences often focused on parables of human struggles resolved through faith.

He put an emphasis on the humanitarian ethic of Mormons, evidenced by his expansion of the church's disaster relief programs around the world, said Armand Mauss, a retired professor of sociology and religious studies at Washington State University.

Monson often credited his mother, Gladys Condie Monson, for fostering his compassion. He said that during his childhood in the Depression of the 1930s their house in Salt Lake City was known to hobos riding the railroads as a place to get a meal and a kind word.

"President Monson always seemed more interested in what we do with our religion rather than in what we believe," Mauss said.

A World War II veteran, Monson served in the Navy and spent a year overseas before returning to get a business degree at the University of Utah and a master's degree in business administration from the church-owned Brigham Young University.

Before being tabbed to join the faith's church's governing Quorum of the Twelve Apostles, Monson worked for the church's secular businesses, primarily in advertising, printing and publishing including the Deseret Morning News.

Monson married Frances Beverly Johnson in 1948. The couple had three children, eight grandchildren and 11 great-grandchildren. Frances died in 2013 at the age of 85.

Throughout his life, Monson was an avid fisherman who also raised homing pigeons, specifically, roller pigeons who twirled as they flew. He was known for his love of show tunes, Boy Scouts and the Utah Jazz.

Monson's legacy will be tied to the church's efforts to hold tight to its opposition of same-sex marriage while encouraging members to be more open and compassionate toward gays and lesbians as acceptance for LGBT people increased across the county.

At Monson's urging, Mormons were vigorous campaign donors and volunteers in support of a measure to ban gay marriage in California in 2008. That prompted a backlash against the church that included vandalism of church buildings, protest marches and demonstrations outside church temples nationwide.

In subsequent years, the church began utilizing a softer tone on the issue. In 2015, the church backed an anti-discrimination law in Utah that gave unprecedented protections for gay and transgender people while also protecting religious freedoms.

But the faith came under fire again in the fall of 2015 when it banned baptisms for children living with gay parents, and instituted a requirement that those children disavow homosexual relationships before being allowed to serve a mission. The changes were designed to avoid putting children in a tug-of-war between their parents and church teachings, leaders said.

The revisions triggered anger, confusion and sadness for a growing faction of LGBT-supportive Mormons who were buoyed in recent years by church leaders' calls for more love and understanding for LGBT members.

One of the most memorable moments of Monson's tenure came in October 2012, when he announced at church conference that the minimum age to depart on missions was being lowered to 19 from 21 for women; and to 18 from 19 for men. The change triggered a historic influx of missionaries, and proved a milestone change for women by allowing many more to serve.

Taking the lead from the previous president, Gordon B. Hinckley, Monson also continued the church's push toward being more open about some of the most sensitive aspect of the faith's history and doctrine. A renovated church history museum reopened in 2015 with an exhibit acknowledging the faith's early polygamous practices, a year after the church published an essay that for the first time chronicled founder Joseph Smith's plural wives.

Other church essays issued during Monson's tenure addressed other sensitive topics: sacred undergarments worn by devout members; a past ban on black men in the lay clergy; and the misconception that Mormons are taught they will get their own planet in the afterlife.

The growth and globalization of the church continued under Monson, with membership swelling to nearly 15.9 million, with more than half outside the United States.

The Mormon church was founded in 1830 in upstate New York by Joseph Smith, who claimed he was visited by God and Jesus while praying in a grove of trees and was called to found the church. Members are known as Mormons because of the keystone scripture, the Book of Mormon.

Mormons believe they are called to share the word of God, specifically their own message of the restored Gospel, through their missionaries. There were 71,000 church missionaries serving around the world at the end of 2016.

Like his predecessors, Monson traveled the world, visiting countless countries to give speeches, dedicate temples and preach to Latter-day Saints. Under his watch, 27 new temples were planned or built.

Monson chose five new members to the Quorum of the Twelve Apostles, a top-governing body that sets policy and runs the worldwide faith's business operations. All five were white and from Utah — a fact that disappointed some Mormons who wanted to see a minority or person from outside the U.S. selected to acknowledge the globalization of the church.

The man expected to take Monson's seat, the 93-year-old Nelson, has been a church apostle since April 1984. Out of respect for Monson, his appointment will not be officially named until after his funeral services.

In keeping with tradition, Nelson will choose two new counselors from the Quorum of the Twelve who will join him to form a three-person "presidency" that is the top of the church's governing hierarchy. Monson's two counselors were Henry Eyring and Dieter Uchtdorf. They will go back to being regular members of the Quorum unless they are chosen again.
