Title page of "Finger Prints" by Francis Galton, 1892. The prints shown are his own. Francis Galton (February 16, 1822 - January 17, 1911) was an English polymath: anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist, psychometrician, and statistician. He was the first to apply statistical methods to the study of human differences and inheritance of intelligence. He introduced the use of questionnaires and surveys for collecting data which he needed for his genealogical and anthropometric studies. He was a pioneer in eugenics, coining the term and the phrase "nature versus nurture". His book Hereditary Genius (1869) was the first social scientific attempt to study genius and greatness. He founded psychometrics (the science of measuring mental faculties) and differential psychology. He devised a method for classifying fingerprints that proved useful in forensic science. He devised the first weather map, proposed a theory of anticyclones, and was the first to establish a complete record of short-term climatic phenomena on a European scale. He also invented the Galton Whistle for testing differential hearing ability. He was knighted in 1909. He lived to be 88 and died of natural causes.
