Biography
Clifford Glenwood Shull (September 23, 1915 – March 31, 2001) was an American physicist who changed the study of crystallography with his work on neutron diffraction techniques. Born in Pittsburgh, Pennsylvania, Shull was educated at Schenley High School, Carnegie Mellon University, and New York University, where he earned a doctorate in physics. His pioneering work in neutron scattering transformed the way scientists examine the atomic structure of materials. He was awarded the Nobel Prize in Physics in 1994, which he shared with Bertram Brockhouse.
Shull's major contribution was the development of neutron diffraction to study crystal structures and magnetic properties. At Oak Ridge National Laboratory and later at the Massachusetts Institute of Technology, he showed how neutrons could be used with remarkable precision to examine atomic arrangements in solids. This technique became crucial for understanding material behavior at the atomic level, particularly in exploring magnetic structures and detecting light atoms that X-ray crystallography struggles to capture.
Throughout his career, Shull received many honors for his scientific contributions. Besides the Nobel Prize, he was awarded the Oliver E. Buckley Condensed Matter Prize in 1956, the Gregori Aminoff Prize in 1993, as well as the Humboldt Research Fellowship and Humboldt Prize. He was also elected as a Fellow of the American Physical Society, recognizing his impact on the physics community.
Shull's work went beyond theoretical physics and had practical uses in materials science, chemistry, and biology. His neutron scattering techniques allowed researchers to study protein structures, look into phase transitions in materials, and gain a detailed understanding of magnetic phenomena. These methods continue to be used in research facilities globally, aiding developments in areas like drug development and new material creation. Shull continued his research and teaching until retiring, passing away in Medford in 2001, leaving a lasting legacy that still impacts modern scientific research.
Before Fame
Growing up in Pittsburgh in the early 20th century, Shull was educated at a time when physics was going through big changes with the development of quantum mechanics and nuclear physics. He went to Schenley High School before studying at Carnegie Mellon University for his undergraduate degree, and then continued with graduate studies at New York University.
The 1930s and 1940s were a great time for physics research, especially in nuclear science, after James Chadwick discovered the neutron in 1932. This discovery opened up new ways to study matter, and Shull jumped into this new field. His early career was during the Manhattan Project era, a time when neutron research was moving forward quickly. This gave him access to neutron sources, which was essential for his later groundbreaking work.
