No, I had not heard of it before, so I looked it up. I did read the entire Smithsonian Magazine article about it. That fire was in 1903 and then in 1911 there was the Triangle Shirtwaist Factory fire in Manhattan. A lesson not learned?
The "Great Chicago Fire" of 1871 killed an estimated 300 people. The Iroquois Theater Fire of 1903 killed at least 600 people.
