Hershey chocolate has become famous around the world. But did you know that the Hershey chocolate factory is only about one hundred years old? And did you know that the founder（创办人）of Hershey Chocolate, Milton Hershey, had many failures （失败）in business before he started his famous company?
Milton Hershey grew up in a farm country of Pennsylvania. Before he started making chocolate, Milton Hershey was a printer. He worked for a small newspaper and then he decided to change a job.
Later he got a job at a candy factory. After working a few years at the factory, he decided to open his own little candy business, His first business had to close down because it was not making money. After that, he traveled to Denver, Colorado, to learn how to make caramels（焦糖）.
He took his new skills back to New York and worked selling candies on the street. But this second business also failed.
Finally, Milton Hershey moved back to the farm country where he grew up. He then experimented（试验）with all sorts of different candies and chocolates. The area where he lived had lots of dairy farms, so he could get plenty of fresh milk easily.
And he could get other supplies（原料）, such as sugar, from nearby Philadelphia. By 1893 he was selling a million dollars worth of caramel candy every year. Since his chocolate-flavored（巧克力风味）caramel was the best-selling, he decided to make chocolate himself.
By experimenting, Milton Hershey learned how to make delicious chocolate by using fresh, sweet milk. His milk chocolates were so popular that he sold his caramel factory and made chocolate only. In 1903, Milton Hershey built a huge chocolate factory and the town of Hershey.
