Robert A. Millikan is best known for his work on the measurement of the elementary electric charge and the photoelectric effect. His most famous experiment, the oil drop experiment conducted in 1909, determined the charge of the electron with high precision. Millikan also contributed to the understanding of the photoelectric effect, demonstrating the quantized nature of light and earning the Nobel Prize in Physics in 1923 for his efforts.
