Mid-century actress Hedy Lamarr made some discoveries that contributed heavily to the use of radar in WW II.

I guess if we want to continue stretching the inclusion criteria I mentioned in the OP, we might even include the high-powered constitutional lawyer and scholar Laurence Tribe, since he did start off, after all, with an undergraduate degree in mathematics from a place called Harvard (graduating summa cum laude at that).
In fact, he has authored many books, some of which may even be in keeping with the original thrust of the OP (although I doubt it).
