Abraham Harold Maslow (April 1, 1908 – June 8, 1970) was an American psychologist who created ⁠Maslow's hierarchy of needs⁠, a theory of psychological health predicated on fulfilling innate human needs in priority, culminating in self-actualization. Maslow was a ⁠psychology⁠ professor at ⁠Brandeis University⁠, ⁠Brooklyn College⁠, ⁠New School for Social Research⁠, and ⁠Columbia University⁠. He stressed the importance of focusing on the positive qualities in people, as opposed to treating them as a "bag of symptoms".⁠ A ⁠Review of General Psychology⁠ survey, published in 2002, ranked Maslow as the tenth most cited psychologist of the 20th century.⁠

Maslow continued his research at Columbia University on similar themes. There he found another mentor in Alfred Adler, one of Sigmund Freud's early colleagues. From 1937 to 1951, Maslow was on the faculty of Brooklyn College. His family life and his experiences influenced his psychological ideas. After World War II, Maslow began to question the way psychologists had come to their conclusions, and although he did not completely disagree, he had his own ideas on how to understand the human mind. He called his new discipline humanistic psychology. Maslow was already a 33-year-old father and had two children when the United States entered World War II in 1941. He was thus ineligible for the military. However, the horrors of war inspired a vision of peace in him leading to his groundbreaking psychological studies of self-actualizing. The studies began under the supervision of two mentors, anthropologist Ruth Benedict and Gestalt psychologist Max Wertheimer, whom he admired both professionally and personally. They accomplished a lot in both realms. Being such "wonderful human beings" as well, they inspired Maslow to take notes about them and their behavior. This would be the basis of his lifelong research and thinking about mental health and human potential.

Maslow extended the subject, borrowing ideas from other psychologists and adding new ones, such as the concepts of a hierarchy of needs, metaneeds, metamotivation, self-actualizing persons, and peak experiences. He was a professor at Brandeis University from 1951 to 1969. He became a resident fellow of the Laughlin Institute in California. In 1967, Maslow had a serious heart attack and knew his time was limited. He considered himself to be a psychological pioneer. He gave future psychologists a push by bringing to light different paths to ponder. He built the framework that later allowed other psychologists to conduct more comprehensive studies. Maslow believed that leadership should be non-intervening. Consistent with this approach, he rejected a nomination in 1963 to be the president of the Association for Humanistic Psychology because he felt that the organization should develop an intellectual movement without a leader.
