Profession: biometricist

A notable scientific polymath, Galton was Darwin’s cousin; they corresponded enthusiastically, intrigued by each other’s researches — Galton’s invention of the field of statistical analysis can be said to have had its roots in Darwin’s work. De Candolle was also an influential correspondent, forcing him to reformulate the nature/nurture debate; other correspondents included Wallace (a friend), Stokes, Rayleigh and Maxwell. Herschel taught him the use of an instrument of his own devising; the young Cattell worked alongside him. Hooker, Spencer and Bentham were all friends, while the statistically-minded Nightingale mooted a professorship with him.
