Museum of Natural History in New York
Naturalist, Rough Rider, and the 26th President of the United States, Theodore Roosevelt is in various museums. There is a wax model of Theodore Roosevelt and his horse, Little Texas. The wax model, according to Robin Williams's character, was made in a mannequin factory in Poughkeepsie, New York.
The Smithsonian Castle
In 1904, while Roosevelt was a former presiding officer of the United States Senate, he was requested by that body to sit for a sculpted bust. He requested that the sculptor was Augustus Saint-Gaudens, but he was sick, so Roosevelt chose James Earle Fraser, his personal assistant. He wanted the bust to look like him, with his head thrown back, and his glasses on. His first impression to The Senate itself failed. The clay statue impressed the president, but The Senate didn't like it. Fraser had done the bust with Roosevelt's Rough Rider outfit on. His second impression was less impressive, but the Senate liked it. It was marble, with bronze painted on it. Made in 1920, it is now sitting in one of the halls in The Smithsonian, in Washington, D.C.
