What words were coined by famous people? Especially if the people were famous for something other than being an author or word coiner. (Is anyone famous just for coining words? I don’t think so.)
The most famous word coiner I know of is Thomas Jefferson, who coined dime, although he spelled it “disme” (the S was silent).
Other non-authors:
Physicist Paul Dirac coined both boson and fermion.
Jean-Baptiste Lamark, most famous for his incorrect theory of evolution, is credited with coining invertebrate
William Herschel, discoverer of Uranus, coined asteroid
Enrico Fermi, another physicist, coined neutrino
Ernest Rutherford, yet another physicist, is credited with proton
Thomas Henry Huxley, early supporter of Darwin, coined agnostic
OK, the above is heavy with scientific terms, but that’s mostly because such terms’ orgins are better documented (usually in a scientific paper) than your run-of-the-mill words. There’s various large groups of scientific terms, such as chemical elements, chemical compounds, minerals, scientific names of plants, animals, and microorganisms, etc. which were sometimes named by famous scientists, but I’m not really interested in those.
You can name famous authors’ coinages if you want. Some that I can think of off-hand are hobbit by Tolkien, chortle, jabberwocky, galumph and perhaps others by Lewis Carroll, cyberspace by William Gibson, nymphet by Nabokov, utopia by Sir Thomas More, grok by Heinlein, and lilliputian, brobdingnagian, yahoo by Jonathan Swift. I’m sure there are many others.
Final note: you may have heard somewhere that Shakespeare coined some large number of words, usually a few thousand[sup]1[/sup]. Well, whoever told you that was giving out misinformation. What that was based on was that Shakespeare was the earliest citation in the OED for that many words. But having the earliest citation is not the same as coining the word. It’s quite possible that Shakespeare didn’t coin any words at all.
[sup]1[/sup] The number credited to Shakespeare has steadily declined as earlier citations have been discovered. No doubt a graph of this number over time would give us a prediction of when it will go to zero. Except that I expect the number will only approach zero asymptotically.
