Abraham Harold Maslow

 
Abraham Harold Maslow ( April 1, 1908 – June 8, 1970) was an American psychologist who was best known for creating 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 Alliant International University, 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."[3] A Review of General Psychology survey, published in 2002, ranked Maslow as the tenth most cited psychologist of the 20th century.
 
Main contributions：
 
①Maslow's hierarchy of needs
Maslow described human needs as ordered in a prepotent hierarchy—a pressing need would need to be mostly satisfied before someone would give their attention to the next highest need. None of his published works included a visual representation of the hierarchy. The pyramidal diagram illustrating the Maslow needs hierarchy may have been created by a psychology textbook publisher as an illustrative device. This now iconic pyramid frequently depicts the spectrum of human needs, both physical and psychological, as accompaniment to articles describing Maslow's needs theory and may give the impression that the Hierarchy of Needs is a fixed and rigid sequence of progression. Yet, starting with the first publication of his theory in 1943, Maslow described human needs as being relatively fluid—with many needs being present in a person simultaneously.
The hierarchy of human needs model suggests that human needs will only be fulfilled one level at a time.
 
②Maslow's hammer
He is also known for Maslow's hammer, popularly phrased as "if all you have is a hammer, everything looks like a nail" from his book The Psychology of Science, published in 1966.
