Courtesy Engineering Computer Network Purdue University Purcell's other contributions ... included a comprehensive theory of nuclear magnetic relaxation (with [Nicolaas] Bloembergen and [Robert V.] Pound - the famous "BPP" paper, one of the most cited references in physics); the concept of negative spin temperatures (with Pound), which was a precursor to the maser and laser; improved spin-echo techniques (with [H. Y.] Carr); and explanations of the absorption and scattering of starlight by interstellar grains. With [Norman F.] Ramsey he was the first to question the conventional assumption (later disproved) that all particle forces are parity symmetric. With Berg he applied physics to biological problems, in their description of the physics of chemoreception and in his classic paper (in The American Journal of Physics) "

Edward Mills Purcell Edward Mills Purcell American physicist who shared, with Felix Bloch of the United States, the Nobel Prize for Physics in 1952 for his independent discovery (1946) 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. During World War II Purcell headed a group studying radar problems at the Radiation Laboratory of the Massachusetts Institute of Technology, Cambridge. In 1946 he developed his NMR detection method, which was extremely accurate and a major improvement over the atomic-beam method devised by the American physicist Isidor I. Rabi. Purcell became professor of physics at Harvard University in 1949 and in 1952 detected the 21-centimetre-wavelength radiation emitted by neutral atomic hydrogen in interstellar space. Such radio waves had been predicted by the Dutch astronomer H.C. van de Hulst in 1944, and their study enabled astronomers to determine the distribution and location of hydrogen clouds in galaxies and to measure the rotation of the Milky Way. In 1960 Purcell became Gerhard Gade professor at Harvard, and in 1980 he became professor emeritus. The same year he received the National Medal of Science.

Purcell and Mary Elizabeth (Mills) Purcell. He attended public schools in Taylorville and Mattoon and received a B.S. degree in electrical engineering from Purdue University in Lafayette, Indiana, in 1933. After a year as an exchange student at the technical university in Karlsruhe, Germany, Purcell began graduate studies in physics at Harvard University, where he received his M.A. degree in 1936 and his Ph.D. degree in 1938. He remained at Harvard as an instructor until 1940. In 1946, he became an associate professor of physics, and in 1949 he became a full professor. During World War II (1939-1945), Purcell supervised a group at the Massachusetts Institute of Technology Radiation Laboratory that was developing techniques for producing and detecting microwaves (short radio waves). He worked with Austrian-born American physicist Isidor Isaac Rabi.

Colleagues and friends worldwide were saddened by the passing of Edward Mills Purcell http://www.news.harvard.edu/gazette/1998/04.09/FacultyofArtsan.html

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.
