John Davidson Rockefeller was an American business magnate and is regarded to be the richest man that ever lived. He made his fortune by founding the successful Standard Oil Company. He ran the company for 27 years and by the time he retired he had $2.9 billion as his total fortune. If this amount is adjusted for inflation then the amount is pegged at $370 billion. In the year 1902, he was worth $200 million which was about 1% of the whole GDP of the U.S.
John d. Rockefeller was born on July 8, 1839 at Richford, New York. His father was a travelling salesman who did not spend much time at home to look after his six children. Young John was always looking for ways to earn money so that he could help his poor family. He was a very well behaved boy who was serious about studying and helping his family. At a young age itself he learnt to earn money by selling potatoes, candy. He then used to lend this money to his neighbours for a small interest.
When his family moved to Cleveland, he attended the Central High School there. After completing his graduation he took a ten- week course in business to get some basic knowledge in order to enter business someday. He was good at Maths and especially accurate in accounting. So he did his first job as an assistant bookkeeper for three months receiving 50 cents per day as salary. He was only 16 years old at that time.
