ruzuzu I think you'll find hernesheir's medical-eponyms list is ripe for plunder. Jan 30, 2013
ry I added Legionnaires' disease because it's lexically pretty unique—a possessive medical eponym named for a group rather than an individual—and found that there are a bajillion possessive-eponymic diseases named for their describers/discoverers (which is presumably one reason sionnach disallowed names on x's y.... Anyway, if anyone wants to add them here, go ahead, but there are a lot.
Edit: there is also a metric f***ton of scientific laws, natural phenomena, and logical paradoxes named in this way. The listers at Wikipedia have done this job already. Jan 30, 2013
ry Oh that is excellent. Another every potential list is an existing list specimen! Well that one disqualifies proper nouns...nor shall I spoliate it the less. thanks! Jan 30, 2013
