Pack attended the University of Utah, where he obtained a degree in mining engineering in 1904. By 1906, he had completed masters and Ph.D. degrees in geology at Columbia University in New York City. In 1906 and 1907, he was a professor of geology and mineralogy at Brigham Young College in Logan. In 1907, he became the Deseret Professor of Geology at the University of Utah, a position he held until his death. In 1918, Pack published Tobacco and Human Efficiency, which has been described as the most "comprehensive or conscientious summation of the case to discourage cigarette use" that had been produced by that date. However, Pack's work on tobacco has been criticized as being tainted with "suppositions" and "moral bias" arising from his status as a Latter-day Saint who believed that avoiding tobacco was a commandment from God. In his later professional life, Pack created a travel company called Utah Intelligence Tours, which specialized in tours of areas in Utah and the Western United States that are of particular geological or paleontological interest. Pack's personal and professional papers are held by the J. Willard Marriott Library at the University of Utah in Salt Lake City.
Church life
Pack was a devout member of the LDS Church. In 1892, he became an elder of the church. In 1896, apostleFrancis M. Lyman ordained him a seventy and in 1897 apostle John W. Taylor ordained him a high priest. Pack and his wife Sadie served as LDS Church missionaries in the ColoradoMission of the church in 1896 to 1898. While on this mission, Pack presided over the Pueblo Conference and later the Colorado Springs Conference. From 1911 to 1916 Pack was the Sunday School Superintendent in the Liberty Stake in Salt Lake City. From 1920 to 1930 he was a member of the high council in the same stake. In 1920, Pack became a member of the Deseret Sunday School Union General Board. In 1932, Pack delivered a series of 28 weekly radio lectures entitled, "The Breadth of Mormonism". During the last years of his life, Pack was the chair of the Gospel Doctrine Committee of the LDS Church. He was a frequent contributor to church magazines, with many of his writings focusing on the scientific justifications for the Word of Wisdom.
Coca-cola and the Word of Wisdom
In 1918, Pack published an article in the church's Improvement Era entitled "Should Latter-Day Saints Drink Coca-Cola?" In the article, Pack reasoned that because Coca-Cola contained caffeine, which is also present in tea and coffee, Latter-day Saints should abstain from Coca-Cola in the same way that they abstain from tea and coffee. Since this time, some Latter-day Saints have believed that drinking Coca-Cola or other caffeinated beverages amounts to a violation of the Word of Wisdom.
Family
Pack married Sadie Grant on November 25, 1896. Sadie Grant Pack was the first counselor to May Anderson in the general presidency of the Primary from 1925 to 1929. The Packs were the parents of four children. His brother Ward E. Pack served in the Utah Territory Legislature.
