1. Read fragments from stories about famous illusionists. For answers to questions choose the names designated by letters A-E. “0” is the example for you. 

A. John Henry Anderson was a Scottish magician who performed in Europe and the United States in the early 19th century. His favourite trick was bullet-catching, but his best remembered for pulling a rabbit from a hat. He didn’t think of the trick first, but he made it popular and there have been variations on it ever since. 
B. Robert Houdin was born in France in 1805. He was originally trained as a clockmaker. He first appeared as a magician in Paris in 1845. He used common objects to create illusions rather than complicated pieces of machinery. He was known as the father of magic and it was from him that Harry Houdini took his name years later. 
C. Howard Thurston was from Ohio. He started by touring and doing card tricks. In 1908 he met the magician, Harry Kellar. Kellar sold him his tricks and Thurston turned them into a 3-hour long magic show. He toured with it for over 20 years. He was well-known for illusions such as the “floating lady”. 
D. Harry Houdini was born Erik Weisz in Budapest, Hungary. Before taking up magic, he worked in a circus. His world-wide fame came from his amazing escapes. One of his most incredible escapes was from a box that was locked, roped, weighted then lowered into water. Late in his career he went to Hollywood and made films, performing his own stunts.
