    Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American physicist who received the Nobel Prize in Physics in 1923 for the measurement of the elementary charge and for his work on the photoelectric effect.

    en.wikipedia.org/wiki/Oil_drop_experiment

    The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). [1] [2] The experiment took place in the Ryerson Physical Laboratory at the University of Chicago. [3] [4] [5] Millikan received the Nobel Prize in Physics in 1923. [6]

    The photoelectric effect: Einstein explained this in 1905 (and later received a Nobel prize for it) using the concept of photons, particles of light with quantized energy. Robert Millikan's oil-drop experiment, which showed that electric charge occurs as quanta (whole units). (1909)

    Robert Andrews Millikan publishes the results of his "oil drop" experiment, in which he precisely determines the electric charge of the electron. Determination of the fundamental unit of electric charge makes it possible to calculate the Avogadro constant (which is the number of atoms or molecules in one mole of any substance) and thereby to ...

    1909 – Robert Millikan: oil-drop experiment which suggests that electric charge occurs as quanta (the electron). 1911 – Ernest Rutherford's gold foil experiment determines that atoms are mostly empty space, and that the core of each atom, which he named the atomic nucleus, is dense and positively charged [1]

    1916 - Robert Millikan conducts experiments and proves the photoelectric effect. 1918 - Jan Czochralski produces a method to grow single crystals of metal. Decades later, the method is adapted to produce single-crystal silicon. 1921 - Einstein awarded the Nobel Prize in Physics for his work on the photoelectric effect.

    Perhaps the following: "In 1916, Robert Millikan published experimental results that supported Einstein's model of the photoelectric effect (not to be confused with Millikan’s famous oil drop experiment)." — Andy Anderson 21:43, 2 February 2020 (UTC) That sounds good to me as a summary.
