The polymath Francis Galton led a privileged and adventurous life, lending his talents to the development of statistical inference, scientific meteorology, psychology, and becoming one of the first to apply the evolutionary theories of his cousin Charles Darwin to human populations, founding the new fields of eugenics and biometrics. The Galton Collection is a miscellaneous assemblage of 15 letters and one photocopy written by Francis Galton to a variety of correspondents. These letters reflect Galton's research in meteorology, statistics, and, to a lesser degree, the heredity of intelligence.
