The Most Generous Man in the World E very morning, billionaire Milton Petrie walked from his New York apartment and bought a newspaper from the ragged old man on the street corner, One morning the man wasn't there. Petrie learned that he was very ill in the city hospital. Immediately he paid his hospital bill and later, when the man died, paid for his funeral.
The old man was just one of many people that Milton Petrie helped with his money. Whenever he read about personal disasters in his newspaper Petrie sent generous cheques, especially to the families of policemen or firemen injured at work. He also sent cheques to a mother who lost five children in a fire, and a beautiful model, whose face was cut in a knife attack. It cost him millions of dollars, but he still had millions left. He said that he was lucky in business and he wanted to help those less fortunate than himself. The nice thing is, the harder I work, the more money I make, and the more people I can help.' Milton Petrie died in 1994, when he was 92. His will was 120 pages long because he left $150 million to 383 people. His widow, Carroll, his fourth and last wife, said his generosity was a result of the poverty of his early years. His family were poor but kindhearted. His father was a Russian immigrant who became a policeman, but he never arrested anyone, he was too kind. He couldn't even give a parking ticket.
The richest, Meanest Womanin the World H enrietta (Hetty) Green was a very spoilt, only child. She was born in Massachusetts, USA, in 1835. Her father was a millionaire businessman. Her mother was often ill, and so from the age of two her father took her with him to work and taught her about stocks and shares. At the age of six she started reading the daily financial newspapers and she opened her own bank account. Her father died when she was 21 and she inherited $7.5 million. She went to New York and invested on Wall Street. Hetty saved every penny, eating in the cheapest restaurants for 15 cents. She became one of the richest and most hated women in the world. She was called 'The Witch of Wall Street'. At 33 she married Edward Green, a multimillionaire, and had two children, Ned and Sylvia. Hetty's meanness was legendary. She always argued about prices in shops. She walked to the local grocery store to buy broken cookies (biscuits) which were much cheaper, and to get a free bone for her much-loved dog, Dewey. Once she lost a two-cent stamp and spent the night looking for it. She never bought clothes and always wore the same long, ragged black skirt. Worst of all, when her son Ned fell and injured his knee, she refused to pay for a doctor and spent hours looking for free medical help. In the end Ned's leg was amputated. When she died in 1916 she left her children $100 million (worth $9.3 billion today). Her daughter built a hospital with her money.
