Houdini - A Magician Among the Spirits

What better time to remember Houdini than Halloween? This is a really, really nice site:

Harry Houdini is still considered today as one of the greatest illusionists and magicians in history. In addition to his fantastic escapes and stunts, he was also well known in the 1920’s for his debunking of fraudulent Spiritualist mediums. In this, modern information about Houdini tends to be skewed. Today, many skeptic organizations have claimed Houdini as one of their own, but this is far from the truth. Unlike these groups, Houdini did not start out attacking fake mediums because he did not believe in the supernatural. In fact, he had gone to them in an attempt to try and contact his dead mother, but found that the mediums he met were often frauds. This was when he turned to exposing them, still searching for the truth.
Before his death, Houdini stated that should it be possible to contact the living from the other side, he would do so. The question remains as to whether or not he actually succeeded. Read more here.
