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.
