Galton, Francis (1822-1911) was an explorer and scientist English with a broad spectrum of interests. He had no university chairs and did most of his research on his own. His many contributions received formal recognition when, at the age of 87, he was awarded the title "Sir" or knight of the Kingdom.
Contribution to Psychology
A Galton can be considered the "father" of differential psychology, applying the principles of his cousin, Darwin, the study of individual differences. This was opposed to the more psychological ideas were spread in his time: that of Wilhelm Wundt.
