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

Explanation:

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).
