Do you know of any instances wherein a wealthy person gave everything to the poor while they were alive and kinda young?

Warren Buffett gave a lot but not everything from what I understand. I don’t know of anyone who’s had the wealth and given it up completely. I am sure there are some senior citizens that have done this, but I think more altruism exist in a wealthy youth doing the same.

I am not asking this question to get specific names. Just if you know of a young person who has done this answer in the affirmative.

I know if anyone has they likely did not do it for the fame, or the grattitude.
