Henry Eyring.

American chemist. Henry Eyring Born in the town of Colonia Juárez in Mexico on February 20, 1901, Henry Eyring was raised in a small but prosperous Mormon community not far from the United States border. His family had settled in the region about twenty years earlier, after leaving Utah to escape anti-Mormon sentiment. Although Eyring had a happy childhood, supported by his father’s career as a cattle rancher, the Mexican Revolution began the year he was born, and by 1912, his family joined nearly five thousand other Mormons from the area in relocating to El Paso, Texas, in an attempt to flee the violence. His family struggled in Texas until his father was able to buy land near Pima, Arizona. Despite the constant relocations and laborious tasks on the family farm, Eyring excelled in school, particularly in mathematics and science. In 1919, he began to study mining engineering at the University of Arizona, working odd jobs in his free time in order to send money home to his family.
