I wonder how much of this ultimately comes down to branding. Einstein has a memorable name, a memorable haircut/photograph, and also managed to have his name become a byword for “genius.”
I'm not familiar with the other names in the parent comment, but do their accomplishments map to Einstein's as far as impact goes? I think they would have to before we consider branding as a main factor in longevity of...reputation?
Of course in the grand scheme of things Einstein was probably more influential, but I was more commenting on the fact that Einstein has become a kind of memetic symbol in himself, a bit like Ché, whereas the others haven’t. (Most people probably can’t even name more than a handful of people from WW1.) Maybe that only happened because his work was so impactful, but does the average person really know much about relativity? I was trying to find a paper that traced how Einstein became synonymous with genius but couldn’t come up with anything.
