I found out about John D. Rockefeller philanthropy acts here, http://www.rockefellerfoundation.org/who-we-are/our-history/. I learned that John D. Rockefeller started donating money to his Sunday school and church from his first job that he had as a teenager. He was inspired by an essay that Andrew Carnegie, a very wealthy philanthropist, wrote in 1889. Rockefeller wrote back to Andrew Carnegie saying, "The time will come when men of wealth will more generally be willing to use it for the good of others." In the same year Rockefeller worked hard with donating his money and ended up giving $35 million in gifts over 20 years so that the University of Chicago could be founded. As time went on his donations kept getting bigger and bigger and in 1901 he created what is now known as Rockefeller University, which promoted education in the United States.
