NIMH History and Impact

In 1946, President Harry S. Truman signed the National Mental Health Act. In addition to its broad purpose of improving "the mental health of the people of the United States," this landmark piece of legislation enabled the founding, three years later, of the National Institute of Mental Health (NIMH). NIMH’s founding represented hope—hope for better understanding and better treatments for people with mental illnesses.
