Which theorist is known for the hierarchy of needs?

The theorist known for the hierarchy of needs is Abraham Maslow. Maslow's hierarchy is a psychological theory that proposes a pyramid of human needs, ranging from basic physiological necessities at the base to self-actualization at the top. This model illustrates that individuals must satisfy lower-level needs, such as food, water, and safety, before they can attend to higher-level needs, including love, esteem, and ultimately, personal growth and fulfillment.

Maslow's work is foundational in understanding motivation in various fields, including education and childcare, as it emphasizes the importance of meeting learners' basic needs as a prerequisite for their development and success. His focus on holistic development and the drive toward achieving one’s potential has significantly influenced educational practices and approaches aimed at fostering well-rounded individuals.
