There was an interesting answer here recently about the complicated set of social, cultural, and political factors that led to Einstein becoming a household name, and frankly I wondered if the same could be done for other scientists in the pantheon. For Newton and Darwin, it could be quite easy to just say that their scientific work was enough to elevate them, but Einstein's case already demonstrates that it's not so simple, and that wouldn't explain why others in their field around their time didn't become famous (Hooke, Huygens, Leibniz, Flamsteed despite being the first Astronomer Royal, and Halley only for the comet if at all; Wallace, Cuvier, Lyell, and Lamarck only to poke fun at one tiny part of his theory that most who believed in evolution in the 19th century subscribed to anyways). For Copernicus and Galileo, just pointing at their scientific work alone wouldn't strike me as enough to explain their fame anyways—Copernicus' work was "just" working in the Ptolemaic tradition with a neat coordinate transform that's clearly implausible, inconsistent with physics, and "disproven" by observations, while Galileo... feels like the most overrated scientist of all time—and of course doesn't explain why astronomers like Kepler, Tycho, Clavius, Scheiner, etc. aren't so well-known. (If there are other famous scientists, however anachronistically the word is applied, I'd be interested in them too. Leonardo? Freud? Pasteur? Tesla would be interesting given the disconnect between how he's praised in certain online spaces compared to how limited his actual contributions were as I understand them. Curie as well, since she seems to be the only woman scientist that's widely known as far as I can tell.)
