The Chicago Field museum has a traveling exhibit on Charles Darwin and his support for the theory of evolution. According to a story in the Chicago Tribune:

Using the naturalist's personal effects, hundreds of specimens, historical photographs, notebooks, manuscripts, living animals and film, the exhibit vividly explains evolutionary theory and re-creates the upper crust world of Victorian science in which Darwin, the son of a wealthy physician and financier, was reared.

The story gives a nice little run down of Darwin's life.
