Robert Millikan, American Physicist

Description: Robert Andrews Millikan (March 22, 1868 - December 19, 1953) was an American experimental physicist. In 1908, he began experiments in which he measured the charge on a single electron. He and his graduate student Harvey Fletcher used the oil-drop experiment to measure the charge of the electron (as well as the electron mass, and Avogadro's number). Millikan took sole credit, in return for Fletcher claiming full authorship on a related result for his dissertation. Millikan went on to win the 1923 Nobel Prize for Physics, in part for this work, and Fletcher kept the agreement a secret until his death.
