The scientist Dr. Charles D. Walcott was the fourth secretary of the Smithsonian, serving from 1907 until 1927. His fascination with geology began when he was thirteen years old and a wagon wheel uncovered a vein of fossils near his home. He traveled all over the world in support of his research, collecting fossils and plants from Canada, South America, and China.
