That might depend on how strict "alone" is. (Perhaps by definition, only having a singular exceptional trait makes it challenging to be renown.) For example, might Fred Rogers count? Or Dolly Parton who, though remembered for many things, has kindness as a core part of her legacy.
I think many people are remembered for being kind, but only by those who knew them very well, such as family and friends.
Well, depending on how you define success, I'd say Trump is successful getting elected as POTUS twice. He sure is a brilliant man to be revered, and the people complaining about his allegations are surely losers... (sarcasm to be certain)
Only total losers whine about such silly things in successful people...
