Robert Galbraith Heath (9 May 1915 – 24 September 1999) was an American psychiatrist.
He followed the theory of biological psychiatry that organic defects were the sole source of mental illness, and that consequently mental problems were treatable by physical means.
He published 425 papers and three books.
One of his first papers is dated 1946.Heath founded the Department of Psychiatry and Neurology at Tulane University, New Orleans, in 1949 and remained its chairman until 1980.
He performed many experiments there involving electrical stimulation of the brain via surgically implanted electrodes.
He placed DBS electrodes into the brains of more than 54 patients.
It has been suggested that this work was financed in part by the CIA and US military.Heath also experimented with the drug bulbocapnine to induce stupor, and LSD, using prisoners in the Louisiana State Penitentiary as experimental subjects.
He worked on schizophrenia patients, which he regarded as an illness with a physical basis.
