Many words have their origins in people’s names, Here's an assortment of terms derived from the names of inventors, Greek gods, historical figures, fictional characters, and other people who did or made something notable enough to have a word base on their moniker.

When something is named after a person or a place or a company, we call that name an eponym. If you know anyone who says "Get me a Kleenex" instead of "Get me a tissue," they are using an eponym every time they have to sneeze. Eponyms are everywhere- in science, medicine, the arts. This list focuses on words that are historically eponyms but are so common that their history of deriving from names has been obscured. In this list, the history of eponyms you didn't realize were eponyms is revealed.
