Abraham Maslow was an American psychologist best known for creating the Maslow's Hierarchy of Needs, a theory that outlines human motivation. This model is often depicted as a pyramid, with basic needs like food and safety at the bottom, and higher-level needs such as self-actualization at the top. Maslow proposed that individuals must satisfy lower-level needs before they can focus on higher-level psychological and self-fulfillment needs. Maslow's work has had a significant impact on psychology, education, and business. His ideas encourage understanding human behavior and motivation, emphasizing the importance of fulfilling basic needs to achieve personal growth and well-being. His theories continue to influence various fields, including human resources and personal development.
