Russell M. Nelson, president of The Church of Jesus Christ of Latter-day Saints, pushed the church away from the nickname 'Mormon', a term that has been used for 200 years.
Nelson became president in 2018 at the age of 93, but his tenure was not uneventful. He proved to be a consequential reformer, streamlining bureaucracy and taking steps toward gender equity.
He told members to "buckle up" and "eat your vitamin pills. It's going to be exciting" during a visit to South America in 2018.
Under his leadership, the church ended its century-long relationship with the Boy Scouts and reaffirmed its opposition to LGBTQ+ relationships and identities. Nelson passed away on September 27, 2025, at the age of 101.
