 | The Pan-American Exposition took place in Buffalo, New York from May 1, 1901 to November 2, 1901. |
| The Smithsonian and the United States National Museum presented exhibitions in 7,500 square feet of space, and spent much of 1900 preparing for the exhibit. The exhibition consisted of displays from all departments, including a Triceratops skeleton, seen at right. |  |
 | The theme of the exposition was peace and progress, and strengthening social community. This peace was crushed with the assassination of President William McKinley while visiting the exposition in September. |
