So far as we know, the idea of a quantised spinning of the electron was put forward for the first time by A. K. Compton (Journ. Frankl. Inst., Aug. 1921, p. 145), who pointed out the possible bearing of this idea on the origin of the natural unit of magnetism. Without being aware of Compton's suggestion, we have directed attention in a recent note (Naturwissenschaften, Nov. 20, 1925) to the possibility of applying the spinning electron to interpret a number of features of the quantum theory of… 
Electron Paramagnetic Resonance Theory
In 1921, Gerlach and Stern observed that a beam of silver atoms splits into two lines when it is subjected to a magnetic field. While the line splitting in optical spectra, first found by Zeeman in
FIFTY YEARS OF SPIN: Personal reminiscences
In a one‐page Letter to the Editor of Naturwissenschaften dated 17 October 1925, Samuel A. Goudsmit and I proposed the idea that each electron rotates with an angular momentum ℏ/2 and carries,
Studies in History and Philosophy of Modern Physics
In December 1924 Wolfgang Pauli proposed the idea of an inner degree of freedom of the electron, which he insisted should be thought of as genuinely quantum mechanical in nature. Shortly thereafter
The Zeeman Effect
In 1896 at Leiden (Holland) Pieter Zeeman (1865–1943) discovered the influence of an external homogeneous magnetic field on the frequencies of spectral lines emitted by a light source, placed in that
Exclusion Principle And Quantum Mechanics
The history of the discovery of the exclusion principle, for which I have received the honor of the Nobel Prize award in the year 1945, goes back to my student days in Munich. While, in school in
Magnetic Moment of the Bound Electron
The magnetic moment of the bound electron is significantly different from that of the free electron. This is true for any binding situation, but particularly pronounced when the electron is bound in
The Nature of the electron
Through investigating history, evolution of the concept, and development in the theories of electrons, I am convinced that what was missing in our understanding of the electron is a structure, into
The Electron and Atomic Structure
In the nineteenth century, chemists and physicists had a completely different image of electricity. The chemists, in contact with a discontinuous and discrete world made of atoms and molecules that
