Perhaps. Here's a quiz: Name a big Philanthropist from 300 years ago. From 150 years ago. From 50 years ago...
What do I win?
What do you remember Alfred Nobel as? John Harvard?
You could make a case for the industrialists, but I'd give good money people can name "Rockafeller Center" before they can name "Standard Oil".
I read about Alfred Nobel in a children's encyclopaedia in primary school; I mostly remember him as the inventor of dynamite who got a crisis of conscience and thus created the Nobel prizes (I didn't think of those as philanthropy, and I'm not sure if the "crisis of conscience" part is factually accurate).
John Harvard, purely name association with Harvard University. I guess I should check his Wikipedia page out.
Edit: It's actually Harvard College. Shows how much I know.
