John Andreas Widtsoe (1872–1952) was a Norwegian-American scientist and apostle who brought a unique synthesis of scientific rigor and religious faith to his Church service. Born on an island among fisher folk in Norway, he emigrated to Utah after his mother’s conversion. He graduated from Harvard with the highest honors and earned his doctorate from the University of Gottingen in Germany.
Widtsoe became renowned for his expertise in irrigation and dry farming, serving as director of the Utah Agricultural Experiment Station and later as president of both Utah State Agricultural College and the University of Utah. He was called to the Quorum of the Twelve in 1921 and later served as president of the European Mission.
A prolific author, Widtsoe wrote A Rational Theology and Evidences and Reconciliations, which addressed common questions about faith and doctrine. His marriage to Leah Dunford, granddaughter of Brigham Young, united him with a distinguished Church lineage. Despite personal tragedy, losing four of his seven children in infancy, he maintained a life of faithful service.
