These were presented in a lecture next to C.V. Raman.  Of course, I didn't draw a sketch of them nor did I happen to write down their names, not anticipating the question to turn up in the following assignment. I remember recognizing the names in the lecture, so they must be famous, but after sifting through a bunch of pictures on Google I can't seem to find a match.

Any assistance is much appreciated

The one on the right is Lord Rayleigh. I know i've seen the one on the left somewhere. Let me think about it.

It all just made sense to me.  The pictures were placed together with Raman.  You just named Rayleigh, so the last one must be Sir George Stokes!

Thanks Corribus!

Yeah I was just about to post that it was probably Stokes. The picture on Wikipedia is when he was older, which threw me for a sec.
