" Clark Leonard Hull (May 24, 1884 – May 10, 1952) was an American psychologist who sought to explain learning and motivation by scientific laws of behavior. Hull is known for his debates with Edward C. Tolman. He is also known for his work in drive theory... Hull is often credited with having begun the modern study of hypnosis. He became interested in the field while taking over a pre-medical course on psychology from Jastrow..After successfully putting a disturbed student into a trance with a gifted hypnotic crystal, he began to research the phenomenon and its medical applications. Dissatisfied with the unscientific nature of the field, Hull sought to bring greater academic rigor through measuring behavior instead of relying on self-reports. While teaching, he encouraged his students to do their research with hypnosis, teaching them the techniques involved.

His work Hypnosis and Suggestibility (1933) was a rigorous study of the phenomenon, using statistical and experimental analysis"
