How many dead billionaires from the last century do you remember and can name without googling?
If it's just the feeling of being remembered for something then there are lots of other things you can do to make people remember you. Nobody remembers the rich merchants from 2000 or 3000 years ago but people still remember the conquerors who changed maps and the artists of those days whose works have been immortalized. Whether you like it or not, someone like Hitler or Tolkien will be more likely to be remembered than someone like Gates and no, Hitler won't still be considered as an irredeemable monster then, just like how people don't get offended by the conquests and massacres by Genghis or Napoleon unless for nationalistic/jingoistic reasons.
