Alfred Russel Wallace worked as a surveyor in South Wales during the 1840s. Wallace became a pioneering natural scientist and founded the science of biogeography, the study of how species are scattered across the planet and how they ended up that way. Wallace co-found the theory of evolution, alongside Charles Darwin, but unlike Darwin, Wallace has become a prisoner of the footnote. The untold stories of our nation’s greatest innovators and scientists will be revealed through an exploration of their work. Engineers, computer pioneers, geneticists and the forgotten father of evolutionary theory are given a voice.
