John van Wyhe is an historian of science. He is the founder and Director of Darwin Online (http://darwin-online.org.uk/) - the largest edition of Darwin's publications and manuscripts ever published, and a Bye-Fellow of Christ's College, Cambridge (Darwin's own college). He recently led the restoration of Darwin's rooms at Christ's College. Dr van Wyhe's research has challenged the long-held view that Darwin held back or kept his theory secret for 20 years (Darwin's delay). His books include Charles Darwin's Notebooks from the Voyage of the Beagle, with Gordon Chancellor and a foreword by Richard Darwin Keynes (Cambridge University Press, 2009), Darwin in Cambridge (Cambridge, Christ's College, 2009) and Darwin (Andre Deutsch, 2008, and National Geographic, 2009).
