ABSTRACT
Sir Francis Galton would be the first to provide systematic investigations into individuals who had achieved eminence and exhibited evidence of high intellectual ability, thus positioning the foundation for the field of gifted education to emerge. Galton's work would clearly help to define and influence psychology through the statistical methods he introduced and theories that influenced individual differences. Although Galton and Charles Darwin were not in close physical contact, they communicated and deeply influenced each other's work. Darwin's work piqued Galton's curiosity toward variabilities and his exiting interests in the methods of biologists and demographers. The biographical methodology and statistical procedures Galton developed were also distinctive and groundbreaking. Galton developed many of the statistical procedures that rendered modern psychology possible, including the concept of regression, correlation coefficients, mean, and medians, using Adolph Quetelet's mathematical concepts, and in collaboration with Karl Pearson.
