  Robert Andrews Millikan 1868-1953
Millikan was appointed associate professor only at the age of 38, in a time when the median American physicist became a full professor at the age of 32.
Millikan emphasized that the very nature of his data refuted conclusively the minority of scientists who still held that electrons (and perhaps atoms too) were not necessarily fundamental, discrete particles.
Early in 1917 Millikan went to Washington to be executive officer of the National Research Council of the National Academy of Sciences, charged with war research on the detection of submarines and other essential problems.

 IEEE - Robert A. Millikan, 1868 - 1953
Robert Andrews Millikan was born in Morrison, Illinois, on 22 March 1868.
Although Millikan had rejected his atom-building hypothesis by 1935, he clung tenaciously to the assumption that some fraction of the primary cosmic radiation could be photons, and developed a new theory that cosmic ray photons originated in the spontaneous annihilation of atoms in interstellar space.
Robert Millikan won the AIEE Edison Medal in 1922 4"?For his experimental work in electrical science." Millikan was an able lecturer, and after he won the Nobel Prize in 1923 he became perhaps the most famous American scientist of his day.

Millikan’s first experience teaching physics spawned a lifelong love of the field, and he remained at Oberlin for two years after he received his undergraduate degree in 1891 to obtain his master’s and continue his role as an instructor.
Millikan spent a significant amount of time in his early years at Chicago trying to establish a solid physics curriculum, for the field of physics was then in its initial stages of development in America.
Millikan’s experiment featured a closed, see-through chamber with two parallel metal plates, one of which was placed toward the top of the chamber and the other at the bottom.

Millikan thought the cosmic ray photons were the "birth cries" of new atoms continually being created by God to counteract entropy and prevent the heat death of the universe.

Millikan was born in 1868, the son of a Midwestern minister.
To Millikan’s surprise, what happened instead was that nearly all of the droplets with their different positive and negative charges dispersed, leaving in view just a few individual droplets that had just the right charge to permit the electric force to come close to balancing the effect of gravity.
To deal with this problem, Millikan assumed, entirely without theoretical basis, as he stressed in his paper, that Stokes’ law could be adequately corrected by an unknown term that was strictly proportional to the ratio of the distance between air molecules to the size of the drop, so long as that ratio was reasonably small.

 Millikan
December 19, 1953, San Marino, Calif., U.S.A. Robert A. Millikan was the most famous American scientist of the 1920s, and the second American to receive the Nobel Prize in physics in 1923 for his study of the elementary electronic charge and the photoelectric effect.
Millikan jumped at it, although he could have had an appointment elsewhere at twice the salary, for Michelson promised that he could spend up to half his time doing his own research, a privilege not granted at most colleges.
Millikan's success was above all attributable to an ingenious device he termed "a machine shop in vacuo." A rotating sharp knife, controlled from outside the evacuated glass container by electromagnetic means, would clean off the surface of the metal used before exposing it to the beam of monochromatic light.

 Science Fair Projects - Robert Millikan
Robert Andrews Millikan (March 22, 1868 - December 19, 1953) was an American physicist who won the 1923 Nobel Prize for Physics primarily for his work in determining the value of the charge on the electron and for the photoelectric effect.
This led Millikan to a further series of measurements which he published in 1913 to reassert his original results.
Though accusations have been made that Millikan was guilty of fraud and pathological science, it seems more likely that he was using his deep experimental insight and subject-matter expertise to reject unreliable observations on sound physical grounds.

Millikan was born on March 22, 1868 in Morrison, Illinois and took a job as a court reporter after he graduated from high school.
Millikan’s oil-drop experiment helped firmly establish that electrons are discrete particles, a claim that was under significant dispute at the time, and gave credence to Niels Bohr's quantum theory of the atom.

Robert Millikan is widely believed to have been denied the 1920 prize for physics owing to Felix Ehrenhaft's claims to have measured charges smaller than Millikan's elementary charge.

Though accusations have been made that Millikan was guilty of fraud and pathological science, some believe that he was using his experimental insight and personal expertise on the subject-matter to reject unreliable observations on sound physical grounds.
Since Millikan's work formed some of the basis for modern particle physics, it is ironic that he was rather conservative in his opinions about 20th century developments in physics, as in the case of the photon theory.

 Robert Millikan : Robert Andrews Millikan
Robert Andrews Millikan (March 22, 1868 - December 19, 1953) was an American physicist who won the 1923 Nobel Prize for Physics primarily for his work in determining the value of the charge on the electron and the photoelectric effect.
His oil-drop experiment to measure the electronic charge (since repeated by generations of physics students) measured the force on tiny charged droplets of oil suspended against gravity between two metal electrodes.
A version of the oil drop experment has subsequently been used to search for free quarks (which would have a charge of 1/3 e), without success.

Millikan once said that he had "milked more than 10,000 cows when I was between 8 and 18, and I curried more than 20,000 horses - and liked it." Millikan attended Oberlin College in Ohio, graduating in 1891.
Millikan taught at the University of Chicago beginning in 1896, then moved to Pasadena, Calif., in 1921 with the promise he could continue his own research.
