Abstract
Albert Einstein’s light-quantum paper was the only one of his great papers of 1905 that he himself called “very revolutionary”. I sketch his arguments for light quanta, his analysis of the photoelectric effect, and his introduction of the wave-particle duality into physics in 1909. I show that Robert Andrews Millikan, in common with almost all physicists at the time, rejected Einstein’s light-quantum hypothesis as an interpretation of his photoelectric-effect experiments of 1915. I then trace the complex experimental and theoretical route that Arthur Holly Compton followed between 1916 and 1922 that led to his discovery of the Compton effect, a discovery that Peter Debye also made virtually simultaneously and independently. Compton’s discovery, however, was challenged on experimental grounds by William Duane and on theoretical grounds by Niels Bohr in the Bohr–Kramers–Slater theory of 1924, and only after that theory was disproved experimentally the following year by Walther Bothe and Hans Geiger in Berlin and by Compton and Alfred W. Simon in Chicago was Einstein’s light-quantum hypothesis generally accepted by physicists.
Einstein's light-quantum hypothesis was initially rejected by physicists, but was accepted after the Bohr-Kramers-Slater theory was disproved experimentally in 1924.
