Edwin S. Shneidman (May 13, 1918 – May 15, 2009) was an American clinical psychologist, suicidologist and thanatologist. Together with Norman Farberow and Robert Litman, in 1958, he founded the Los Angeles Suicide Prevention Center where the men were instrumental in researching suicide and developing a crisis center and treatments to prevent deaths.

In 1968, Shneidman founded the American Association of Suicidology and the principal United States journal for suicide studies, Suicide and Life-Threatening Behavior. In 1970, he became Professor of Thanatology at the University of California, where he taught for decades. He published 20 books on suicide and its prevention.

Shneidman was born in York, Pennsylvania in 1918 to Russian Jewish immigrants. His father was a merchant with a department store.^[1] As a child, Shneidman attended local public schools.

He went to the University of California Los Angeles (UCLA) for undergraduate and graduate work, earning a master's degree in psychology in 1940. His education was interrupted by World War II, and he served in the Army.^[1]

Afterward, Shneidman returned to graduate school, earning a doctorate in clinical psychology from the University of Southern California (USC). As an intern, he studied schizophrenia, then thought to be environmentally caused, at the Veterans Administration hospital in Brentwood.^[1] He was an atheist.^[2]

In the late 1940s, Shneidman became interested in the problem and mystery of suicide while working at the Veterans Hospital in Brentwood.^[1] Becoming involved in trying to understand one case, he conducted much research into suicide notes and motivations. He formulated many terms to use in such study: as his researcher colleague Norman Farberow wrote of him: "He is one of the brightest, sharpest, most intellectually gifted persons I have ever known," and later spoke of Shneidman's ability to coin new terms, such as suicidology,^[3] psychological autopsy,^[4] psychache,^[5] and pseudocide notes^[6] (notes collected from non-suicidal subjects and compared with writings in a 1957 study).

In 1958 with Norman Farberow and Robert Litman, he founded the Los Angeles Suicide Prevention Center. The psychoanalyst Litman acted as executive director. At a time when suicide was little studied and discussion of it was avoided, they were pioneers. Shneidman helped them get funding for the project from the National Institutes of Health (NIH). In 1966 Shneidman began working as chief of a national project at the NIH to establish suicide prevention centers, and increased their number from a few to 100 in 40 states in three years.^[7][1]

In 1968 Shneidman founded the American Association of Suicidology and its bi-monthly journal called Suicide and Life-Threatening Behavior.

Changes in ideas of medical care led to the end of the national project and decreases in funds for suicide prevention centers. The Los Angeles Center was combined with programs of the Didi Hirsch Community Mental Health Center.^[1] More recently, treatment of people with depression and bipolar disorder, disorders often associated with suicide, has depended chiefly on the biological model and psychiatric drugs.

In 1970 he became the first professor of thanatology at UCLA, where he taught until 1988.^[7] He continued to write and mentor other psychologists throughout his life.

Shneidman married Jeanne, and they had four sons: David William, Jonathan Aaron, Paul Samuel, Robert James^[1][7] He died at the age of 91 on May 15, 2009, in Los Angeles, California.^[1]

In this text, Shneidman coins the term "psychache"—intense emotional and psychological pain that eventually becomes intolerable and which cannot be abated by means that were previously successful—as the primary motivation for suicide

• The Suicidal Mind (1998)

Shneidman investigates three suicide attempts—one was completed --Schneidman taught the word "successful" was too sanguine and therefore inappropriate to use in reference to suicide, another led to death from infection several months later, and another uncompleted—and the common features of suicidal persons. An appendix features a questionnaire completed by one of his patients, measuring her level of "psychache".
