John D. Rockefeller was born on July 8, 1839 in Richford, New York. He was involved in the American oil business, he was a business magnate as well as a philanthropist. At the age of 16, he became an assistant bookkeeper, and joined a business partnership with his brothers at 20. He later bought them out of this partnership and founded Rockefeller and andrews with his brother and Samuel Andrews. Instead of drilling for oil however, his focus was on refining oil so it could be used in kerosine and gasoline due to their growing importance. As he continued his wealth greatly increased as he ended up controlling more than 90% of all the oil in the U.S.
