Eponym

An eponym is the name of a person, whether real or fictitious, who has (or is thought to have) given rise to the name of a particular place, tribe, discovery, or other item. An eponymous person is the person referred to by the eponym. In contemporary English, the term eponymous is often used to mean self-titled. The word eponym is often used for the thing titled. Stigler's law of eponymy suggests that Eponyms are usually false, i.e., things are rarely named after the person who discovered or invented them.
