On Feb. 28, you published my letter regarding your editorial decision to run Felix Gillette’s article about the Washington Monument. The opinions I expressed in that letter were entirely my own. Though I identified myself as a curator of a future exhibition at the National Building Museum, I did not mean to imply that the museum endorsed, or even knew of, any of the views contained in it. I apologize to you and to your readers for any confusion or misunderstanding that I may have caused.
