     The man of many secrets-Harry Houdini-was one of the greatest American entertainers in the theater this

century. He was a man famous for his escapes-from prison cells, from wooden boxes floating in rivers, from

locked tanks full of water. He appeared in theaters all over Europe and America. Crowds came to see the great

Houdini and his "magic" tricks.

     Of course, his secret was not magic or supernatural powers. It was simply strength. He had the ability to

move his toes as well as he moved his fingers. He could move his body into almost any position he wanted.

     Houdini started working in the entertainment world when he was 17, in 1891. He and his brother Theo

performed card tricks in clubs in New York. They called themselves the Houdini Brothers. When Harry

married in 1894, he and his wife Bess worked together as magician and assistant. Bur for a long time they

were not very successful. Then Harry performed his first prison escape in Chicago in 1898. Harry persuaded

a detective to let him try to escape from the prison, and he invited the local newspapermen to watch.

     It was the publicity (宣传) that came from this that started Harry Houdini's success. Harry had fingers

trained to escape from handcuffs and toes trained to escape ankle chains. But his biggest secret was how he

unlocked the prison doors. Every time he went into the prison cell, Bess gave him a kiss for good luck-and a

small skeleton key, which is a key that fits many locks, pass quickly from her mouth to his.

     Harry used these prison escapes to build his fame. He arranged to escape from the local prison of every

town he visited. In the afternoon, the people of the town would read about it in their local newspapers, and

in the evening every seat in the local theater would be full. What was the result? Worldwide fame and a name

remembered today.
