Edward Mills Purcell Edward Mills Purcell August 30 March 7 ) was an American physicist who shared the Nobel Prize for Physics for his independent discovery ( ) of nuclear magnetic resonance in liquids and in solids. Nuclear magnetic resonance (NMR) has become widely used to study the molecular structure of pure materials and the composition of mixtures. Born and raised in central Illinois, Purcell received his B.S.E.E. in electrical engineering from Purdue University , followed by his M.A. and Ph.D. in physics from Harvard University . After spending the years of World War II working at the MIT Radiation Laboratory on the development of microwave radar, Purcell returned to Harvard to do research. In , he discovered nuclear magnetic resonance (NMR) with his students Pound and Torrey. NMR provides scientists with an elegant and precise way of determining chemical structure and properties of materials, and is widely used in physics and chemistry. It also is the basis of magnetic resonance imaging (MRI), one of the most important medical advances of the 20th century. For his discovery of NMR, Purcell shared the Nobel Prize in physics with Felix Bloch of Stanford University . Purcell also made contributions to astronomy as the first to detect radio emissions from neutral galactic hydrogen, affording the first views of the spiral arms of the

March 10, 1997 Dr. E.M. Purcell, 84, Shared Nobel for Work on Hydrogen r. Edward M. Purcell, who made it possible to "listen" to the whisperings of hydrogen throughout the universe, died Friday in Cambridge, Mass. He was 84. The cause was respiratory failure, a son said. Purcell had been associated with Harvard University since 1936, retiring from there in 1977 as the Gerhard Gade University Professor. In 1952, he shared the Nobel Prize in Physics for discovering a way to detect the extremely weak magnetism of the atomic nucleus. The method, measuring nuclear magnetic resonance, is widely used to study the structure of molecules and to measure magnetic fields. The previous year, he and a graduate student, Harold I. Ewen, used an antenna on a Harvard roof for the first detection of radio emissions from clouds of hydrogen in space. As had been predicted, the emissions were at a wavelength of 21 centimeters, or 8.3 inches. Because hydrogen is the dominant material of the universe, such observations became a prime astronomical tool. As the most prominent landmark in radio astronomy, that wavelength has also been the focus of efforts to detect signals from any civilizations on other worlds. Purcell was a tall, thin man who retained his boyish appearance and diffidence into middle age. On scientific matters, however, he was outspoken, serving as a science adviser to Presidents Dwight D. Eisenhower, John F. Kennedy and Lyndon B. Johnson.

[an error occurred while processing this directive] April 09, 1998 SEARCH THE GAZETTE Faculty of Arts and Sciences Memorial Minute Edward Mills Purcell Colleagues and friends worldwide were saddened by the passing of Edward Mills Purcell, Gerhard Gade University Professor, Nobel Laureate, and giant of 20th century physics. Purcell grew up in the Illinois towns of Taylorville and Mattoon, where his father managed a regional telephone company, and where the youthful Edward discovered the joys of tinkering with discarded telephone equipment. He was inspired also by the elegant articles in the Bell System Technical Journal - "It was a glimpse into some kind of wonderful world where electricity and mathematics and engineering and nice diagrams all came together," he recalled fifty years later. He entered Purdue intending to become an electrical engineer, but by the time he graduated with a BSEE he knew that he was to become a physicist. He spent a year as an exchange student in pre-war Germany, studying physics at Karlsruhe. On the voyage to Europe he met a fellow exchange student, Beth Busser, who became his wife three years later. The return voyage brought him to Harvard, where he earned his Ph.D. under Kenneth Bainbridge, and where he remained throughout his career. During the war Purcell headed the group working on very short wavelength radar at the MIT Radiation Laboratory, where microwave radar was being urgently developed to contribute decisively to the Allied victory. In 1945 Purcell (with Pound and Torrey) observed nuclear magnetic resonance (NMR), in an after-hours experiment while still completing work on the classic 27-volume series of books on radar. Though initially used in physics, NMR has been applied powerfully as an analytic method for elucidating chemical structure and materials properties. The Nobel prize winning discovery is also the basis of medical resonance imaging (or MRI), now routinely used as an elegant and non-invasive diagnostic tool, producing beautifully detailed images of the body's interior.

The red shed that had been affixed Isaac F. Silvera, Thomas D. Cabot Professor of the Natural Sciences, is pictured by the shed which adjoined Jefferson Lab. The Cosmic Ray Shed was torn down on May 25. (Staff photos Stephanie Mitchell/Harvard News Office) to the side of Lyman Laboratory of the Department of Physics for almost 70 years appeared to be no different - a minor wood building that seemed uncomfortably out of place next to the far more substantial Lyman, which was built out of brick and mortar in 1931. Yet the shed's appearance belied the important role it played in 20th century physics. More descriptively called the "cosmic-ray shed," it was the setting for some great scientific discoveries. But on May 25, the cosmic-ray shed took part in its final physics experiment: inertia. The shed met the force of a bulldozer to make room for the new Laboratory for Interface Science and Engineering (LISE) being built adjacent to the Gordon McKay Laboratory.

Purcell, Edward Mills Edward Mills Purcell was born in Taylorville, Illinois, U.S.A., on August 30, 1912. His parents, Edward A. Purcell and Mary Elizabeth Mills, were both natives of Illinois. He was educated in the public schools in Taylorville and in Mattoon, Illinois, and in 1929 entered Purdue University in Indiana. He graduated from Purdue in electrical engineering in 1933. The discovery of nuclear magnetic resonance absorption was made just after the end of the War, and at about that time Purcell returned to Harvard as Associate Professor of Physics. He became Professor of Physics in 1949; his present title is Gerhard Gade University Professor. He has continued to work in the field of nuclear magnetism, with particular interest in relaxation phenomena, related problems of molecular structure, measurement of atomic constants, and nuclear magnetic behaviour at low temperatures. He has made some contribution to the subject of radioastronomy. He is a Fellow ofthe American Physical Society, a member of the National Academy of Sciences, of the American Academy of Arts and Sciences, and of the President's Science Advisory Committee under President Eisenhower from 1957-1960 and under President Kennedy as from 1960.

BIOGRAPHICAL MEMOIRS National Academy of Sciences Edward Mills Purcell By Robert V. Pound E DWARD MILLS PURCELL, NOBEL laureate for physics in 1952, died on March 7, 1997, of respiratory failure at his home in Cambridge, Massachusetts. He had tried valiantly to regain his strength after suffering leg fractures in a fall in 1996, but recurring bacterial lung infections requiring extended hospitalizations repeatedly set back his recovery. Two of the best known of Purcell's many outstanding scientific achievements are his 1945 discovery with colleagues Henry C. Torrey and Robert V. Pound of nuclear magnetic resonant absorption (NMR), and in 1951 his successful detection with Harold I. Ewen of the emission of radiation at 1421 MHz by atomic hydrogen in the interstellar medium. Each of these fundamental discoveries has led to an extraordinary range of developments. NMR, for example, initially conceived as a way to reveal properties of atomic nuclei, has become a major tool for research in material sciences, chemistry, and even medicine, where magnetic resonance imaging (MRI) is now an indispensable tool. Radio spectroscopy of atoms and molecules in space, following from the detection of the hyperfine transition in hydrogen as the first example, has become a major part of the ever-expanding field of radio astronomy. Purcell made ingenious contributions in biophysics, as exemplified by his famous analysis of life at low Reynolds numbers, which described the locomotion of bacteria in water. In astronomy, he made important contributions to the study of the alignment of interstellar grains. As a teacher he had a great influence on many students whom he advised and who sat in his beautifully crafted courses at Harvard. His introductory textbook on electricity and magnetism set a new standard of scholarship. Finally, Purcell was looked to as a most valued advisor and consultant throughout his professional life, having served on innumerable committees, including two periods of service on the President's Science Advisory Committee in the administrations of Presidents Eisenhower, Kennedy, and Johnson.
