Like his brother, Hardeen was skeptical of the claims of spiritualist
mediums. With his friend
Julien Proskauer, he exposed the fraudulent methods of the mediums. Houdini, in his
will, requested that all his
files be given to Hardeen and destroyed ("I give, devise and bequeath to my brother, Theodore, Professionally known as "Hardeen" all my theatrical effects, new mysteries and illusions and accompanying paraphernalia, to be burnt and destroyed upon his death.") On August 15, 1927, Hardeen's Brooklyn home was broken into and some of Houdini's apparatuses were damaged. Later that year, Hardeen burned all of Houdini's personal files in a furnace in his basement. In 1945, while planning on writing a book about his brother, Hardeen went to Manhattan's
Doctors Hospital for a simple operation. He unexpectedly died of complications while recovering from the procedure. He was 69 years old. ==Legacy==
