In my opinion, an altruist is someone who selflessly helps others, cares for others with dedication-sacrificing their own interests, benefits, well-being for the sake of others or for the sake of society as a whole.
A philanthropist also selflessly helps others, cares about them, but without sacrificing their interests, benefits, and well-being.
In other words, an altruist is someone who is willing to give away the last crumb of bread, a philanthropist is someone who donates from an overabundance of this bread.
