From Wiki:
"The Miller effect was named after John Milton Miller. When Miller published his work in 1920, he was working on vacuum tube triodes; however, the same theory applies to more modern devices such as bipolar and MOS transistors."
I'm a fan of naming things after their discoverers (or inventors)--Johnson noise, Fano bandwidth, Nyquist theorem, Fourier transform, Eccles-Jordan flip flop, Widlar/Brokaw bandgaps, Gilbert cell, Widlar/Wilson/Thompson current mirrors, .... It makes it clear to students that these things had to be invented by somebody, so maybe they could have a circuit or theorem or algorithm named after them. Inspiring, that's what it is. (*sniff sniff*)
Of course some folks are so productive that using their name isn't specific enough, e.g. calling a theorem "Gauss's" or "Euler's" doesn't narrow things down very much. ;)
