Shown below is a search I did on America's heavyweight innovators, picking a few from each of the last three centuries. (In so doing, I reviewed the Atlantic's list of "The Top 50 Greatest Breakthroughs Since the Wheel," making sure I didn't miss an important name. Update February 2020: I ran the same Ngram search this morning that I did more than six years ago and the results are slightly updated but my conclusions below unchanged.)
Some observations:
1. Henry Ford, who died in 1947, remains the dominant presence among American innovators. Only Bill Gates was able to take a run at Ford around 2000, but since then has seen his interests shift from entrepreneurship to philanthropy. Edison, Carnegie, and Rockefeller are also long-term heavyweights. America remains a culture defined, at least in the written word, by the automobile and computer.
