Did they really spell Stuyvesant that way in New York back in 1910?
My two daughters who graduated from Stuyvesant High School (founded 1904) know very well how the old Dutchman spelled his name.
Google leads me to several sources that say that the theater was founded in 1907, designed by somebody or other for the “impresario David Belasco”–and that it was named the “Stuyvesant Theatre” when it opened, but that it’s been known as the Belasco Theatre since 1910. And the New York Times archive has several articles, about the building and opening of the new theater, and it’s spelled “Stuyvesant” in each. So I guess it’s just the semi-literate ad copywriter and editor in Salt Lake City. Oh, those provincials!
At least they got “Theatre” right–that’s how it was spelled in all the Times articles.
