Historian Everett Mendelsohn was intrigued. In the middle of writing a review of an annual survey of academic publications in the History of Science, he marveled that an article in that volume contained almost 40 pages’ worth of references to works on Darwin published in just the years between 1959 and 1963. Almost 200 works published in a handful of years – no single figure in the history of science commanded such an impressive academic following. Yet Mendelsohn noted that, paradoxically, no one had written a proper biography of Darwin by 1965. Oh sure, there was commentary. Lots of commentary. But so many of the authors were retired biologists who had a tendency toward hagiography or, the opposite, with axes to grind.
