Rockefeller donated more money to charity at the end of his life than any other person ever. This is based on how much the dollar was worth back then. When the worth of the dollar is compared he gave a much higher percentage of his money away. He donated millions and millions of dollars to missionaries and relief groups around the country as well as donated large sums of money to churches, schools and libraries.
Rockefeller helped fund Tuskegee university as well as moorhouse college so that so that they could stay open. He also started the first modern medical school in China. He believed that God gave him the money so he believed that it was his duty to help others with his money.
