The Strong Museum has one of only four known original signed manuscripts of the famous poem, "A Visit from St. Nicholas," better known as "'Twas the Night Before Christmas." Although sometimes disputed, New York scholar Clement Clark Moore (1799-1863) allegedly wrote the poem in 1822. Published anonymously in a Troy, New York newspaper in 1823, the poem became an instant success. This copy is signed by Moore, dated August 1853, and reads at the bottom "Written many years ago; I cannot say exactly when."
