     1 Jean Paul Getty was born in 1892 in Minneapolis, Minnesota. He became a millionaire when he was only 24. His father was wealthy, but he did not help his son. Getty made his millions alone. He made his money from oil. He owned Getty Oil and over 100 other companies. The Fortune magazine once called Getty “the richest man in the world.”

     2But money _________. He married five times and divorced five times. He had five children but spent little time with them. None of Getty's children had very happy lives.

     3Getty loved to make money and loved to save it. In spite of his great wealth, Getty was miser. Every evening, he wrote down every cent he spent that day. He even put pay telephone in the guest's bedrooms in his house so he could save money on phone bills.

     4 In 1973, kidnappers took his 16-year-old grandson, and demanded a large amount of money for his safe return. Getty's son asked his father for money to save his child. But Getty refused. The kidnappers were merciless and Getty’s son made repeated requests for help from his father. Finally, Getty agreed to lend the money, but at 4 percent interest.

     5 Getty started a museum at his home Malibu, California. He bought many important and beautiful pieces of art for the museum. When Getty died in 1976, the value of the collection in the museum was $1 billion. He left all his money to the museum. After his death, the museum grew in size. Today it is one of the most important museums in the United States. Getty made a large fortune in his life, but he gave his money to the art world because he wanted people to learn about and love art.
