Is there someone you miss whose memory should be honored? Here are some ways.


On his amazing invention: Merryman told NPR’s “All Things Considered” in 2013 that Kilby challenged the design team to create the calculator. “He says, we’d like to have some sort of computing device, perhaps to replace the slide rule. It would be nice if it were as small as this little book that I have in my hand.” “Silly me, I thought we were just making a calculator, but we were creating an electronic revolution.”

What they said about him: "I have a Ph.D. in material science and I've known hundreds of scientists, professors, Nobel prize-winners and so on. Jerry Merryman was the most brilliant man that I've ever met. Period. Absolutely, outstandingly brilliant." "He had an incredible memory and he had an ability to pull up formulas, information, on almost any subject." –Vernon Porter, former Texas Instruments colleague and friend, according to the Associated Press
