Derivation
Historical acclaim for discoveries is often allotted to persons of note who bring attention to an idea that is not yet widely known, whether or not that person was its original inventor – theories may be named long after their discovery. In the case of eponymy, the idea becomes named after that person, even if that person is acknowledged by historians of science not to be the one who discovered it. Often, several people will arrive at a new idea around the same time, as in the case of calculus. It can be dependent on the publicity of the new work and the fame of its publisher as to whether the scientist's name becomes historically associated.
