As can be seen from the photo, thousands of people came out to watch Houdini jump into the Charles River. The little lady behind Harry is Bess.
from 1907 to see an actual picture of the theatre. The green building on the postcard is Keiths.
The location was 547 Washington St. Boston, MA. I had to go back and recheck some information because it gets a little confusing. However, I think I have it correct now.
The original Keith's opened on March 24, 1894 (hmm, Houdini's birthday just by coincidence) It was next to the Bijou Theatre and the Boston Theatre, all Keith properties. Keith's New Theatre as it was called was sold in 1926 and this property became the Apollo Theatre and then the Lycric Theatre and then the Normandie and then the Laffmovie Theatre. It was torn down in the 1950s.
The Boston Theatre, which was owned by Keith's was torn down and a new Keith's was built in 1926-27 called The Keith's Memorial Theatre. This is now the Boston Opera House. David Copperfield plays the Boston Opera House when he is in town, but Houdini never performed at that location.
