Notes
He is the father of Henry B. Eyring.

Henry Eyring (February 20, 1901 – December 26, 1981) was a Mexican-born American theoretical chemist whose primary contribution was in the study of chemical reaction rates and intermediates.

A prolific writer, he authored more than 600 scientific articles, ten scientific books, and a few books on the subject of science and religion. He received the Wolf Prize in Chemistry in 1980 and the National Medal of Science in 1966 for developing the Absolute Rate Theory or Transition state theory of chemical reactions, one of the most important developments of 20th-century chemistry. Several other chemists later received the Nobel prize for work based on it, and his failure to receive the Nobel prize was a matter of surprise to many. The Royal Swedish Academy of Sciences apparently did not understand Eyring's theory until it was too late to award him the Nobel; the academy awarded him the Berzelius Medal in 1977 as partial compensation. Sterling M. McMurrin believed he should have received the Nobel Prize but was not awarded it because of his religion.

He was also elected president of the American Chemical Society in 1963 and the Association for the Advancement of Science in 1965.

History

Eyring, a third generation Mormon, was reared on a cattle ranch in Colonia Juárez, Chihuahua, a Mormon colony, for the first 11 years of his life. In July 1912, the Eyrings and about 4,200 other immigrants were driven out of Mexico by violent insurgents during the Mexican Revolution and moved to El Paso, Texas. After living in El Paso for approximately one year, the Eyrings relocated to Pima, Arizona, where Henry completed high school and showed a special aptitude for mathematics and science. He also studied at Gila Academy in Thatcher, Arizona, now Eastern Arizona College, where one of the pillars at the front of the main building still bears his name, along with that of his brother-in-law, Spencer W. Kimball, later president and prophet of The Church of Jesus Christ of Latter-day Saints (LDS Church). Eyring's father was the last member of the LDS Church to practice polygamy, which he did until 1954 when one of his two wives died.

By 1919, Eyring had received a state fellowship to the University of Arizona, where he received degrees in mining engineering, metallurgy, and chemistry. He subsequently pursued and received his doctoral degree in Chemistry from the University of California, Berkeley in 1927 for a thesis entitled: A Comparison of the Ionization by, and Stopping Power for, Alpha Particles of Elements and Compounds.

After a review of his dissertation, Princeton University recruited Eyring as an instructor in 1931. He would continue his work at Princeton until 1946 when he was offered a position as dean of the graduate school at the University of Utah. The chemistry building on the University of Utah campus is now named in his honor.

Eyring married Mildred Bennion. She was a native of Granger, Utah who had a degree from the University of Utah and served for a time as head of the physical education department there. She met Eyring while pursuing a doctorate at the University of Wisconsin. They had three sons with his wife, Mildred Bennion. The oldest, Edward M. "Ted" Eyring is a chemistry professor at the University of Utah. Henry B. Eyring is a general authority of the LDS Church. Harden B. Eyring is a higher education administrator for the State of Utah.

Religious beliefs

Eyring was a member of The Church of Jesus Christ of Latter-day Saints throughout his life. His views of science and religion were captured in this quote: "Is there any conflict between science and religion? There is no conflict in the mind of God, but often there is conflict in the minds of men." Eyring also feared overeager defenders of faith would discard new scientific findings because of apparent contradictions. He encouraged parents and teachers to distinguish between "what they know to be true and what they think may be true," to avoid clumping them together and "throwing the baby out with the bath."

As a member of the LDS Church, he served as a branch president, district president, and, for over twenty years, a member of the general board of the Deseret Sunday School Union. His son Henry B. Eyring is currently an Apostle and member of the First Presidency of the church.
