On September 24, 1926, Houdini appeared as part of special "Midnight Benefit" show to aid the Red Cross and victims of the devastating 1926 Miami hurricane. The show was given at the Metropolitan Theatre in Boston. In the advert on the right you can see Houdini's name below Al Jolson and Georgie Jessel. Houdini was playing his 3 Shows in One for the third and final week at the Majestic Theater at this time (featuring Buried Alive).
On the day of the benefit the Boston Globe ran an article ("GREAT BENEFIT SHOW FOR FLORIDA TONIGHT") that singled out Houdini for a mention. But what's curious is the paper states he "is under the care of his physician."
The surprise of the evening will be the appearance of Harry Houdini, who promises the committee that he will show them how to extract more donations from the audience. Houdini, who is appearing at the Majestic, is under the care of his physician, but despite this handicap the mystifier will be on hand to do his stuff for this call of charity.
This is the first I've heard of Houdini being ill or injured in September 1926. This was before his accident in the Water Torture Cell and well before the famous punch. Two days earlier he spoke at an Advertising Club of Boston luncheon at the Hotel Bellevue, and the Boston Globe's detailed account of that gathering makes no mention of a doctor. Indeed, Houdini seemed to be in top form, even stating, "I'm 52, but physically I'm 35."
One possibility is this physician was with him for training purposes as this was only a few days before his second submerged casket test at the Worcester YMCA. Other than that, this one has me stumped and, of course, intrigued!
