Did Robert Millikan come up with the atomic structure?

No, Millikan devised and performed extremely simple and elegant experiments to measure the charge on an electron.


The link describes the experiment better than I could do. Their experiment was so sophisticated (and this in 1921) that their reported value, #1.5924(10) xx 10^(-19)*C# is quite comparable to the best current value, #1.602176487(40)xx10^(-19) *C#. Their experiment on oil drops found that the charge were small integer multiples of this value (because the oil drops were charged with 1 or several extra electrons).
