Gordon Allport

Gordon Allport was a pioneer in personality psychology and the study of prejudice. He is best known for his trait theory, which categorized personality into cardinal, central, and secondary traits. Allport's work provided a scientific framework for understanding individual differences and the structure of personality. Additionally, his classic book 'The Nature of Prejudice' remains a seminal text in social psychology, exploring the roots of intergroup conflict.

His balanced approach, which integrated both individual and social perspectives, continues to influence personality assessment and social research in the modern era.
