    Tony Wheeler was born to travel. His father worked for an airline. For the first 16 years of his life, Tony and his family lived in many different countries.

    In the early 1970s, Tony met a young woman named Maureen. They soon married. Before getting jobs, Tony and Maureen wanted to travel. They took a year-long trip from England, through Asia, to Australia. On the trip, they visited places like Iran(伊朗), India, and so on.

    When Tony and Maureen arrived in Australia, people asked many questions about their trip. To answer these questions, Tony wrote a book called Across Asia on the Cheap. The book told people about different countries' weather, customs(风俗)，and places to visit. But unlike other travel books then, Tony Wheeler's book also talked about places most tourists did not go. He also wrote about unusual things to see and do. The book was very popular.

    Tony and Maureen started a company called Lonely Planet… They continued travelling. They wrote books for each place they visited. Today, 800 people work for Lonely Planet. The company has over 650 books. Tony Wheeler, the great traveller, still writes about travels to many places and will bring us more surprises.
