Piltdown Man
The Piltdown Man hoax is thought to have been perpetrated by Charles Dawson, an archaeologist, geologist and fossil collector for the British Museum. However, no one is quite certain who was involved. There are a number of other suspects, including Sir Arthur Smith Woodward, Keeper of the British Museum's Natural History department, and Pierre Teilhard de Chardin, a paleontologist and Jesuit theologian.
