The amazing coincidence of Einstein's birth and Hawking's death both occurring on Pi Day is akin, in long odds but delightful symmetry, with Thomas Jefferson and John Adams, long-time rivals and later pen pals, both dying on the same day, July 4, 1826 -- and, for the perfect icing on that cake, that date being the 50th anniversary of the signing of the document -- the Declaration of Independence -- to which they were both so indelibly attached. The universe gives us some fantastical stories. I wonder, if you gave Einstein, Hawking, and Euler the task of calculating the odds of both of those coincidences, which one would hit the buzzer first.

Rats, I got almost all of it, but despite having just recovered from the flu I couldn't get 119A without turning to Wordplay. Makes me sick.

I made what was admittedly a lucky guess with B as the cross-letter, but I don't get 85D NABOB or 96A BAE. I'd be happy to have someone elucidate.

Also, point of minor interest, as soon as I completed the puzzle, all of the triple letter rebi (rebususususes??) converted to single letter squares. I honestly don't recall if that's a standard feature of genus rebus.
