Francis Galton was a Victorian statistician, a human geneticist, one of the most remarkable men of his generation – and the half-cousin of Charles Darwin. Many of his ideas had a profound effect on modern science, not least his work that essentially laid the foundations for modern statistics. For that, we owe Galton a sincere debt of gratitude. (Unfortunately, he was also active in the burgeoning eugenics movement, for which we certainly do not.)
