Sir Francis Galton

Sir Francis Galton.

Sir Francis Galton publishes his work, Hereditary Genius, which claims that intelligence is an inherited trait and that high levels of intellectual achievement follow genealogical lines.
Galton also makes the first scientific attempt to measure intelligence. In 1888, he sets up an "anthropometric laboratory" in which he uses the rather dubious measures of visual acuity, auditory accuracy, and breathing capacity to assess levels of intelligence.
