Below are 10 of the most famous psychologists in history who have made an indelible mark on psychology as we know it today.

1. Ivan Pavlov (1849-1936)

Ivan Pavlov was a Nobel prize-winning Russian physiologist who is well known for his work in classical conditioning, which involves learning to associate an unconditioned stimulus that already brings about a particular response with a new, conditioned stimulus. Although Pavlov was not a psychologist, his work has had a major influence on the field, and his discovery and research on reflexes influenced the development of behaviorism.

2. William James (1842-1910)

William James was an American philosopher and psychologist who was also trained as a physician. He is often referred to as the “Father of American Psychology” and was the first educator to offer a psychology course in the US.

3. Sigmund Freud (1856-1939)

Sigmund Freud is one of the most famous figures in psychology. He was an Austrian neurologist who became known as the father of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and psychoanalyst.

5. Alfred Adler (1870-1937)

Alfred Adler was an Austrian psychiatrist and philosopher who developed the first holistic theory of personality, psychopathology, and psychotherapy. Adler believed that when we feel encouraged, we act in a connected and cooperative way because we feel capable and appreciated. Adler’s theory and practice have been applied in child growth and development. Alder’s followers believe that helping children feel significant and competent is crucial to alleviating difficult behaviors.

6. Carl Jung (1875-1961)
