Henri-Robert (4 September 1863 – 12 May 1936) was a French lawyer, historian, and member of the Académie française in 1923.
Born of unknown parents and probably illegitimate, Henri-Robert was admitted to the Paris bar in 1885 and rose to become a celebrated criminal defense lawyer. He defended a young woman named Gabrielle Bompard in a sensational 1889 murder trial, calling in Georges Gilles de la Tourette as an expert witness on hypnotism.[1] He also defended the fraudster Thérèse Humbert, and the serial child killer Jeanne Weber, twice.[2] In 1903, a Paris correspondent for The New York Times described him as "an exceptionally successful lawyer... the favorite advocate of the criminal classes (who) has already saved innumerable heads from the guillotine".[3]
