Isidor Rabi receives the Nobel Prize in Physics "for his resonance method for recording the magnetic properties of atomic nuclei". Because of the war, Rabi could not go to Sweden to receive the prize. There was, instead, a celebration oraganized at the Waldorf Astoria, in Ney York City.

Isidor Rabi receives his Ph.D in Physics from Columbia University with a dissertation on the magnetic properties of crystals.

Isidor Rabi spends two years in a travelling fellowship through Europe, working with great scientists such as Sommerfeld, Bohr, Pauli, Stern, and Heisenberg. He spends the majority of his time in Stern’s laboratory in Germany, where he observes and performs experiments using the Stern-Gerlach molecular beam method.

Unsatisfied with his studies, Isidor Rabi decides to find a job rather than continue on to graduate school. After three years far from university, he decides to return at Cornell University to do graduate work in chemistry.

Isidor Rabi's family moves to the United States in 1899 first in a Jewish ghetto in the Lower East Side of Manhattan, then, when Rabi is already nine years old, in the Jewish community of Brownsville, in Brooklyn.

Isidor Rabi is appointed Lecturer in Theoretical Physics at Columbia University, becoming Professor of Physics in 1937. During these years, with Gregory Breit, he develops the Breit-Rabi equation and predicts that the Stern–Gerlach experiment could be modified to confirm the properties of the atomic nucleus.

Isidor Rabi starts graduate work in chemistry at Cornell University, but an year later he decides to move to Columbia University and to turn to physics.

Isidor Rabi is born in Rymanów, then Austria-Hungary. He is the son of David Rabi, a tailor, and his wife Janet Teig. His parents are a very faithful Jewish pair.

Isidor Rabi leads a research program where he invents the atomic- and molecular-beam magnetic-resonance method of observing atomic spectra, a precise means of determining the magnetic moments of fundamental particles, a powerful tool for the testing of theories in quantum electrodynamics. This method has wide applications to atomic clock, to nuclear magnetic resonance, and to the maser and laser.

Isidor Rabi marries Helen Newmark.

Isidor Rabi receives a full scholarship for attending Cornell University where he starts studying electrical engineering, but ends earning a B.S. in chemistry. The chemistry course in qualitative analysis prompts him to switch to chemistry.

Isidor Rabi dies at his home in Riverside Drive, Manhattan, of cancer at the age of 89.

In 1940 Isidor Rabi is granted leave from Columbia to work as Associate Director of the Radiation Laboratory at the Massachusetts Institute of Technology on the development of radar and the atomic bomb. After the war he becomes a forthright opponent of atomic weaponry, describing that as "wrong on fundamental ethical principles". Rabi is one of the founders of the Brookhaven National Laboratory on Long Island in 1945.

Isidor Rabi attends the Manual Training High School in Brooklyn. During his classes he is extremely concentrated; but at home he mainly pursues his personal interests as, for example, reading history books. During his senior year, he achieves the highest grade in the state on the New York Regents history exam.

Isidor Rabi returns to Columbia University as Executive Officer of the Physics Department. During these years he increases the strength of the department, especially in high-energy and microwave physics. In 1957 he becomes Higgins Professor of Physics and University Professor in 1964. While at Columbia, he originates also the concept of the CERN international laboratory for high-energy physics in Geneva. Rabi retires in 1967.
