Georges Albert Édouard Brutus Gilles de la Tourette (30 October 1857 – 26 May 1904) was a French medical doctor. He was a neurologist, but the field did not exist during his time. His main work in medicine were in the fields of hypnotism and hysteria. He is the namesake of Tourette syndrome, a neurological condition identified by physical and verbal tics. By 1885, Gilles de la Tourette published nine cases with similar symptoms. His mentor, Jean-Martin Charcot, renamed the syndrome "Gilles de la Tourette's illness" in his honour.
