Some of the brightest people on the planet daily toil in relative obscurity. They grab no headlines and don't show up in who's-who photos. They simply work hard on innovations, driven only by the intrinsic rewards of discovery and dedication. If they were in it for fame or fortune, they would have given up a long time ago. Without them, we would be without technical, science, and social innovations. The next time you benefit from or hear about any kind of breakthrough, thank someone you will never meet or hear of.
