Houdini did not live to be 100. However, New York City was the site of an outdoor Houdini feat to mark his 100th birthday in 1974. Doug Henning--at the time a largely unknown Canadian magician--marked Houdini's centennial by doing Metamorphosis in front of the Plaza Hotel on Fifth Ave. and 59th St. with his assistant Dale Soules. As you can see from the photos in the Daily News account below, he drew a nice crowd (click to enlarge).
Henning was in New York preparing The Magic Show at the Cort Theater. The musical opened two months later and became a Broadway hit, kicking off what we now consider the Second Golden Age of Magic. Maybe we can say it all started on Houdini's 100th!
