Who proposed the hierarchy of needs?

The renowned psychologist Abraham Maslow is credited with proposing the influential hierarchy of needs theory. Introduced in his 1943 paper "A Theory of Human Motivation," Maslow's theory posits that human beings are motivated by a series of needs arranged in a hierarchical pyramid. At the base are physiological needs (e.g., food, water, shelter), followed by safety needs, then love and belonging, esteem needs, and finally, at the apex, self-actualization. Maslow suggested that lower-level needs must be largely satisfied before individuals can pursue higher-level needs. This framework has significantly impacted various fields, including education, management, and psychology, by providing a comprehensive understanding of human motivation and development. While Carl Rogers, Sigmund Freud, and Erik Erikson are also prominent figures in psychology, they are associated with different foundational theories. Rogers developed client-centered therapy, Freud is known for psychoanalysis, and Erikson for his stages of psychosocial development. Maslow's unique contribution lies in his systematic organization of human needs into a progressive hierarchy.
