John D. Rockefeller and Leland Stanford.

Explanation:

John D. Rockefeller who was one of the wealthiest men of his time, was inspired by Andrew Carnegie's philantrophic ventures so much so that he gave away over $500 million to various causes such as education and scientific ventures. Bear in mind that this figure is unadjusted for inflation which means in today's dollars he gave away tens of billions.

Leland Stanford who founded Stanford University along with his wife, donated most of his wealth as well in honor of his son who passed away.
