Whew! For a moment there I was afraid that this was another RIP!
This guy is truly amazing! He was the inventor of the "Pyrochrome" processing, and his book on Optical Security Techniques is one of those that I am always looking for on Amazon!

Clever guy indeed, and the first to show that the composite refractive index of a mixture of two materials is related not to the refractive index of each, but to the electrical polarizability of each.

Kaveh, do you have more information on this?

John, I probably have the paper on this somewhere, but have to dig it up. He used the "Lorenz-Loretnz" equation (yes, two people!) and his experimental data were amazingly well matched to theory. OK, I think it is this one:
R.L. van Renesse and F.A.J. Bouts, Efficiency of Bleaching Agents for Holography, Optik, Vol. 38, (No. 2), 1973, pp. 156-168.
(Certainly those were the authors.)
If you email van Renesse he can probably send you a pdf.
