Almost every kid in this country has ever eaten Hershey chocolate. But do you know that the Hershey chocolate factory is more than one hundred years old? And do you know that the father of Hershey Chocolate, Milton Hershey, had many failures in business before he started his famous company?

Milton Hershey grew up in Pennsylvania. Before he became interested in making chocolate, he worked as a printer for a small newspaper at first, and then decided that printing was not the right job for him.

Then he worked at a candy factory in Lancaster. After working a few years there, he decided to open his own little candy business near Philadelphia. His first business failed because it was not making money. After that, he went to Denver 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 his second business also failed.

Finally, Milton Hershey moved back to Pennsylvania where he grew up. He then experimented with all sorts of different candies and chocolate. By 1893 he was selling a million dollars worth of caramel candy each year. Since his chocolate-flavored(巧克力味的) caramels were the best selling, he decided to make chocolate himself.

By experimenting, Milton Hershey discovered how to make delicious chocolate. The area where he lived had a large and easy supply of milk and sugar, which helped him succeed in his chocolate business. In 1903, Milton Hershey built a huge chocolate factory and a town to go with it.

Today, the town of Hershey is still the home if the factory that Milton Hershey built. And if you ever visit, you can smell delicious chocolate smells just bu driving through the town.

The factory is not so hard to find, Just travel down Cocoa Avenue until you get to East Chocolate Avenue. Turn right at the traffic lights and just follow your nose.
