Millikan, Robert Andrews (1868-1953) US physicist, who after more than 20 years at the University of Chicago went to the California Institute of Technology in 1921. His best-known work, begun in 1909, was to determine the charge on the electron in his oil-drop experiment, which led to the award... 

Robert Andrew Millikan determined the charge of an electron using an oil-drop experiment. 

Nobel-prize-winning American physicist Robert Andrews Millikan counterbalanced the gravitational force on an oil droplet by an upward electric force due to an applied electric field acting on isolated charges on the droplet. As commonly observed today in the student laboratory, the droplet can be observed through a telescope to reverse its downward fall as the electric force is increased sufficiently to overcome the force of gravity. 

In the science laboratory of the University of Chicago worked Robert Andrews Millikan, a man about C.T.R. s age. He had carefully read accounts of the work already done in the Cavendish Laboratory at Cambridge. Then he set to work to construct a new piece of apparatus. It consisted of two brass plates about one-third of an inch apart. In the center of the upper plate he bored a hole the diameter of a needle, and illuminated the space between the plates by a powerful beam of light. He connected the brass plates to a battery which supplied ten thousand volts. 

Physicist Robert Andrews Millikan (1868-1953), educated at Columbia University, was Professor of Physics at University of Chicago, 1910, Director of Norman Bridge Laboratory of Physics at Caltech, 1921, and winner of the Nobel Prize in Physics, 1923. He was the leader in recruiting top-quality scientists and engineers to come to Caltech as faculty members.

Robert Andrews Millikan, an American physicist, determined the amount of charge on an electron. He was awarded the Nobel Prize in 1923 for this work. 

Born in Morrison, Illinois, Robert Andrew Millikan was the second son of the Reverend Silas Franklin Millikan and Mary Jane Andrews. When Millikan was seven, his family moved to Maquoketa, Iowa, where he attended high school. In 1886 he entered Oberlin College in Ohio. In 1887 he enrolled in several classics classes there, and because he did quite well in Greek, at the end of his sophomore year, he was asked to teach an introductory-level physics class. Fie enjoyed teaching physics and accepted a two-year teaching post at Oberlin upon graduation in 1891. It was during this period that he developed an even keener interest in physics. 

There were good reasons for preferring the latter alternative and assuming the cathode-ray particle to be much smaller than any atom. By 1911 this was proven definitely by the American physicist Robert Andrews Millikan (1868-1953), who succeeded in measuring, quite accurately, the minimum electric charge that could be carried by a particle.
