Extractions: Edward Purcell Interview (June 14, 1991) This interview is part of the Rad Lab Collection Edward Mills Purcell served as a group leader of radar frequencies and systems research on the X-band and K-band projects, (groups 41 and 42) which involved the development of magnetrons at Radiation Lab from 1940 to 1945. He spent his last year at Rad Lab in the Office of Publication writing the Rad Lab Technical Series. Purcell reflects on his work on counter mortar radar and K-band experimental radar. He also takes the opportunity to clear Rabi's name in the controversy around K-band wavelength choice by describing how that decision was made and taking full responsibility for the problems they encountered. Describing the atmosphere at Rad Lab as ebullient, he fondly recalls the pressure of war deadlines, the challenge of learning by doing, and his impressions of DuBridge, Loomis and Rabi.

Dr. E.M. Purcell, 84, Shared Nobel For Work On Hydrogen edward mills purcell was born in Taylorville, Ill., on Aug. 30, 1912.His father was general manager of a regional telephone company http://almaz.com/nobel/physics/obit-purcell.html
Extractions: March 10, 1997 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.

Extractions: 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. His interest had already turned to physics, and through the kindness of Professor K. Lark-Horovitz he was enabled, while an undergraduate, to take part in experimental research in electron diffraction. As an Exchange Student of the Institute of International Education, he spent one year at the Technische Hochschule, Karlsruhe, Germany , where he studied under Professor W. Weizel. He returned to the United States in 1934 to enter Harvard University , where he received the Ph.D. degree in 1938. After serving two years as instructor in physics at Harvard, he joined the Radiation Laboratory, Massachusetts Institute of Technology , which was organized in 1940 for military research and development of microwave radar. 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. This experience turned out to be very valuable. Perhaps equally influential in his subsequent scientific work was the association at this time with a number of physicists, among them

Extractions: in full EDWARD MILLS PURCELL (b. Aug. 30, 1912, Taylorville, Ill., U.S.d. March 7, 1997, Cambridge, Mass.), 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.

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.

Extractions: Bìhem druhé svìtové války vedl Purcell skupinu, která vyvíjela radary v Radiation Laboratory na MIT (Massachusetts Institute of Technology) v Cambridge. V roce 1946 vyvinul metodu NMR (Nuclear Magnetic Resonance - jaderná magnetická rezonance). V látce vloené do vnìjího magnetického pole konají elementární jaderné magnetické momenty precesní pohyb. Tento precesní pohyb mùe rezonovat s elektromagnetickou vlnou vyslanou na látku. Pomocí jaderné magnetické rezonance lze zkoumat uspoøádání atomù ve sloitých molekulách a tato metoda se stala také nedílnou souèástí lékaøských diagnostických metod. Purcell se stal profesorem fyziky na Harvardu v roce 1949 a pomocí radaru citlivého na vlnovou délku 21 cm zachytil záøení atomárního neutrálního vodíku z mezihvìzdného prostoru. V roce 1960 se stal profesorem na Harvardu a v roce 1980 se stal emeritním profesorem tamté. Ten samý rok dostal National Medal of Science.
