Russell M. Nelson, president of The Church of Jesus Christ of Latter-day Saints, died at his home in Salt Lake City after 10 p.m. local time, church officials said.

Nelson was the oldest serving president in the history of the LDS Church and died peacefully, the church said.

Nelson served as an apostle beginning in 1984 and became the church’s leader in 2018. His ministry spanned more than 30 countries and U.S. territories.

He was also an internationally recognized heart surgeon who helped develop an artificial heart and lung machine.

“So deeply saddened and yet, once again, so very happy for him…. For me, that would be prayer for President Nelson and all those that mourn,” Glenn Beck said on X.

Nelson is survived by his wife Wendy, 10 children, 57 grandchildren and more than 160 great-grandchildren.
