I learned a few days ago that Pro. John A. Tvedtnes of BYU passed on June 3, 2018. He was 77 years old. He was a prolific writer, publishing many books on the ancient Near East and its relationship with the Book of Mormon. He was until his retirement in 2007, the senior research scholar at the Neal A. Maxwell Institute for Religious Scholarship at BYU. His work on the Book of Abraham was especially important to me, as I have long held a deep interest in that work. His biography, written by his friend Daniel Peterson, is here.
