Russell M. Nelson, president of The Church of Jesus Christ of Latter-day Saints, pushed the church away from the nickname 'Mormons', a term used for 200 years.
Nelson, a former heart surgeon and longtime church leader, became president in 2018 at the age of 93. Despite his advanced years, he proved to be an energetic leader, streamlining bureaucracy and taking steps toward gender equity.
Visiting South America in 2018, he told members to "buckle up" and "eat your vitamin pills. It's going to be exciting."
During his presidency, Nelson ended the church's century-long relationship with the Boy Scouts and reaffirmed its opposition to LGBTQ+ relationships and identities. He died on September 27, 2025, at the age of 101, leaving behind a legacy as a consequential reformer.
