Harold Clayton Urey was born in Walkerton, Indiana, on April 29, 1893. After graduation from high school, he taught in country schools in Indiana and Montana for three years, and then entered the University of Montana, majoring in zoology with a minor in chemistry. His first independent research project was a study of the protozoa in a slough of the Missoula River. Shortly after he graduated, the United States entered World War I, and Urey went to an industrial chemical laboratory in… Expand
