The honor of having your own Google Doodle is bestowed upon only a few very special individuals like Gregor Mendel, Alexander Calder and Lucille Ball. Today's entrant celebrates the 84th birthday of the late Robert "Bob" Noyce, co-inventor of the microchip. After co-founding Fairchild Semiconductor and Intel, he mentored younger engineers to earn the nickname "the Mayor of Silicon Valley." Surf on over to the Google homepage and you'll see its logo imprinted over a microprocessor, which Bob helped to birth.
