One name looms large for the general public when the word "evolution" is mentioned: Charles Darwin. Of course, others are quite aware that Alfred Russel Wallace co-discovered the theory of evolution with Darwin, a fact that the prescient individuals at the Natural History Museum in Britain are well aware of. In 2002, the Museum was able to purchase a rather large collection of Wallace's personal and related family papers, correspondence, photographs, and other items from the Wallace family. With the generous support of the Mellon Foundation, the Museum has digitized approximately 200 items from this collection and placed them online at this site. Visitors may wish to start by looking over a brief biography of Wallace, and then taking a look at the detailed chronology of the main events in his life. The "Online Collection" section is where the heart of the material lies, as visitors can view Wallace's original notes on evolution, read about his encounters with spiritualism, and a number of touching letters that include a note on Wallace's troubles with his cats, Crumpet and Flunkie.
