The American Physical Society began on May 20, 1899, when a group of 36 physicists met at Columbia University to set up a society "to advance and diffuse the knowledge of physics". At the start the APS only held scientific meetings. In 1913 it took over the "Physical Review," which had begun in 1893 at Cornell University. The "Physical Review" was followed by "Reviews of Modern Physics" in 1929 and by "Physical Review Letters" in 1958.
