Abraham Maslow
April 1, 1908 — Brooklyn, New York
Abraham Harold Maslow was an American psychologist who fundamentally changed how the world understands human motivation. His Hierarchy of Needs — presented as a pyramid from basic survival to self-actualization — remains one of the most widely recognized frameworks in psychology, business, education, and popular culture.
Brooklyn to Academia
Born on April 1, 1908, in Brooklyn, New York, to Russian Jewish immigrant parents, Maslow grew up in a difficult household and later described his childhood as "psychopathologically abnormal." He sought refuge in books and education, eventually studying psychology at the University of Wisconsin under behaviorist Harry Harlow — famous for studies on attachment in rhesus monkeys. Early in his career Maslow conducted research on dominance behavior and sexuality, but he grew increasingly dissatisfied with behaviorism's focus on external stimuli and began searching for a more humanistic framework to explain what drives people.
The Hierarchy of Needs
In his landmark 1943 paper "A Theory of Human Motivation," Maslow proposed that human needs form a hierarchy of five levels: physiological (food, water, shelter), safety, love and belonging, esteem, and at the apex, self-actualization — the drive to realize one's fullest potential. The idea was that lower needs must be substantially met before higher needs become motivating. Though the famous pyramid graphic was popularized by later textbooks rather than Maslow himself, the framework became ubiquitous in management training, educational theory, counseling, and everyday life. It shifted psychology's focus from pathology toward growth, peak experiences, and what makes humans flourish.
Did You Know?
Maslow developed much of his thinking about self-actualization by studying exemplary individuals rather than mentally ill patients. His subjects included Abraham Lincoln, Albert Einstein, Eleanor Roosevelt, and Harriet Tubman — people he believed demonstrated the fullest expression of human potential. He called them "self-actualizers" and noticed common traits: acceptance, spontaneity, creativity, and deep interpersonal relationships.
Humanistic Psychology and Lasting Influence
Maslow cofounded humanistic psychology — sometimes called the "Third Force" after behaviorism and psychoanalysis — alongside Carl Rogers and others. He served as president of the American Psychological Association in 1967 and spent his final years at the Eupsychian Management Institute, applying his ideas to business leadership. His 1954 book Motivation and Personality remains in print and widely assigned. He died of a heart attack on June 8, 1970, leaving a body of work that continues to shape how we think about human potential and organizational behavior.
