Edmund Jacobson

Edmund Jacobson ( born April 22, 1888 in Chicago, † January 7, 1983 ) was an American physician and physiologist and the founder of the Progressive Muscle Relaxation and biofeedback.

Edmund Jacobson was the son of Morris Jacobson, a native of Strasbourg real estate agent, and his wife, Fannie, born in Iowa.

Jacobson began his research in 1908 at Harvard University. He was able to prove the link between excessive muscular tension and various physical and mental disorders through extensive scientific investigations. He noted that tension and effort always accompanied by a shortening of the muscle fibers and recognized the relaxation as the exact opposite of arousal states. Jacobson found that the reduction in muscle tone reduces the activity of the central nervous system and relaxation is suitable as a general remedy for psychosomatic disorders and prophylaxis.

After 20 years of research, he published his results in 1929 for the first time, first as literature for physicians. His major work, "You must relax" turned to a general audience and published in 1934 It was in 1990 under the title " relaxation as therapy - Progressive Relaxation in theory and practice." First published in German language. Jacobson deepened his research in the years 1936-1960 at the Laboratory of Clinical Physiology in Chicago. During his life he published 64 scientific studies and a total of eight books on relaxation.
