Why did Felix Bloch get a Nobel Prize?
Felix Bloch (23 October 1905 – 10 September 1983) was a Swiss-American physicist and Nobel physics laureate who worked mainly in the U.S. He and Edward Mills Purcell were awarded the 1952 Nobel Prize for Physics for "their development of new ways and methods for nuclear magnetic precision measurements."
When the atoms return to their original positions, they emit electromagnetic radio waves with frequencies characteristic of different elements and isotopes. In 1946, Felix Bloch and Edward Purcell developed methods for precise measurement, making it possible to study different materials’ compositions.

Felix Bloch’s father, Gustav Bloch (1868-1947) was a Moravian grain merchant, his mother Agnes née Mauer (1878-1970) was from Vienna. After attending the city school in Zurich from 1912 and graduating from the Kantonsschule Rämibühl, Felix Bloch began studying mechanical engineering; between 1924 and 1927 he studied mathematics and physics at the S...
After intermediate stations in Utrecht and Haarlem in the Netherlands, Felix Bloch became an assistant to Werner Heisenberg in Leipzig in 1931. He habilitated in 1932 with a thesis “Zur Theorie des Austauschproblems und der Remanenzerscheinung der Ferromagnetika” (On the Theory of the Exchange Problem and the Remanence Phenomenon of Ferromagnetics...
From the summer of 1942, Bloch worked on the Manhattan Project in Los Alamos, to which he had been invited by Robert Oppenheimer, whom he still knew from Berkeley. He worked in Seth Neddermeyer’s group on the implosion version of the atomic bomb. According to his own statements, however, he considered his work done at the end of 1943 and left. He d...
In 1944, Rabi was awarded the Nobel Prize in physics for this work on the topic. About two years later, Felix Bloch and Edward Mills Purcell expanded the technique for use on liquids and solids, for which they shared the Nobel Prize in Physics in 1952. The three scientists, Rabi, Bloch, and Purcell observed that magnetic nuclei could absorb RF ener...
When CERN was being set up in the early 1950s, its founders were searching for someone of stature and international prestige to head the fledgling international laboratory, and in 1954 Professor Bloch became CERN’s first Director-General. After leaving CERN, he returned to Stanford University. Bloch died in Zürich in 1983 at age 77. Leonard Susskin...
The Nobel Prize in Physics 1952 was awarded jointly to Felix Bloch and Edward Mills Purcell "for their development of new methods for nuclear magnetic precision measurements and discoveries in connection therewith"
Felix Bloch and Edward Purcell demonstrated how manipulating and analysing the movement of these subatomic spinning tops could be useful in identifying the structure of molecules in solids and liquids.
Felix Bloch was a Swiss-born American physicist who shared (with E.M. Purcell) the Nobel Prize for Physics in 1952 for developing the nuclear magnetic resonance method of measuring the magnetic field of atomic nuclei. Bloch’s doctoral dissertation (University of Leipzig, 1928) promulgated a quantum.
Edward Mills Purcell, American physicist, shared the 1952 Nobel Prize in physics with Swiss-born American physicist Felix Bloch (1905-1983) “for their development of new methods for nuclear magnetic precision measurements and discoveries in connection therewith.”
