Along with publishing several books, Schneidman founded the Los Angeles Suicide Prevention Center and the American Association of Suicidology.
As the obit points out, Schneidman believed suicidal tendencies could often begin to be untangled by asking two simple questions: "Where do you hurt?" and "How may I help you?"
Schneidman lived to 91. In this audio piece, he shares a quote in which he describes showing up to the ER at the age of 90, disappointed to still be alive. Realize he hadn't died, he sobbed, because he was ready for death.
He also often wrote about enriching life by contemplating death and dying and was a proponent of open dialogue on both topics, arguing that people should be unafraid of death.
