Galton's 100: an exploration of Francis Galton's imagery studies

Francis Galton has long been recognized as a pioneer of experimental psychology. The work on which this reputation is based occupied him for several years – broadly, from 1877 to 1884 – at the peak of his scientific productivity. This period of Galton's career has, however, attracted relatively little attention from historians, and few have made full use of the materials available for its study.
