Short Summary
Harold Urey was an American physical chemist known for his pioneering work in isotope separation and the discovery of deuterium, a heavy isotope of hydrogen. His groundbreaking research earned him the Nobel Prize in Chemistry in 1934. Urey's work had profound implications across various scientific fields, including chemistry, physics, and planetary science. He is also recognized for his contributions to the development of the atomic bomb during World War II and for his theories on the origin of life on Earth.
Early Life & Education
Harold Clayton Urey was born on April 29, 1893, in Walkerton, Indiana, to a family with a strong educational background. His father was a minister, and his mother was a teacher, which instilled in him a lifelong passion for education and science. Urey attended the University of Montana, where he earned a bachelor's degree in zoology in 1917. Despite his initial interest in biology, he shifted his focus to chemistry and completed his Ph.D. in 1923 at the University of California, Berkeley, where he studied under renowned chemist Gilbert N. Lewis. His education laid the foundation for his future scientific achievements.
Career Highlights
Harold Urey's career was marked by significant contributions to both theoretical and practical chemistry. After completing his Ph.D., he worked at Columbia University, where he discovered deuterium in 1931. This discovery not only earned him the Nobel Prize but also influenced the development of nuclear power and weaponry. During World War II, Urey was a part of the Manhattan Project, contributing to the development of the atomic bomb. Following the war, he joined the University of Chicago, where he shifted his focus to cosmochemistry and theories related to the origin of the solar system and life on Earth.
