Edward Mills Purcell was a well-known American physicist
Edward Mills Purcell born at
In 1937, Purcell married Beth C. Busser. They had two sons, Dennis and Frank.
He died on March 7, 1997.
E.M. Purcell was born on August 30, 1912 in Taylorville, Illinois, U.S. His parents, Edward A. Purcell and Mary Elisabeth Mills, were both natives of Illinois.
He did his schooling in public schools in Taylorville and in Mattoon, Illinois and joined the ‘Purdue University’ in 1929.
He received his BSEE in electrical engineering from ‘Purdue University’, followed by his M.A. and Ph.D. in physics from ‘Harvard University’.
Purcell worked as an instructor in physics for two years in Harvard after receiving his Ph.D. from the university.
Later, he joined the Radiation Laboratory, ‘Massachusetts Institute of Technology’. Here, he became Head of the Fundamental Developments Group in the Radiation Laboratory, which was concerned with the exploration of new frequency bands and the development of new microwave techniques.
After staying at Massachusetts during World War II years, he returned to Harvard to pursue research.
In December 1946, he discovered nuclear magnetic resonance (NMR) with his colleagues Robert Pound and Henry Torrey.
He received the ‘Nobel Prize’ in physics for his discovery of nuclear magnetic resonance in 1952.
Purcell discovered nuclear magnetic resonance in liquids and solids. NMR is widely used to study the molecular structure of pure materials and the composition of mixtures. It is widely used in physics and chemistry for determining the chemical structure and properties of materials. NMR also serves as the basis of magnetic resonance imaging (MRI), one of the most important medical advances of the 20th century.
He was the first to detect radio emissions from neutral galactic hydrogen, the famous 21 cm line due to hyperfine splitting. Measurements of the 21 cm line are still an important technique in modern astronomy.
Purcell was the author of the innovative introductory text ‘Electricity and Magnetism’. The book, a Sputnik-era project funded by an NSF grant, was influential for its use of relativity in the presentation of the subject at this level. The book has educated and inspired a generation of physicists.
