sadiste

from the name of the Marquis de Sade, known for his libertine writings evoking the pleasure of causing harm to others. The term 'sadism' was coined or recorded in the 1834 posthumous reissue of the Universal Dictionary of the French Language by Boiste; it was reused with 'sadistic' in 1862 by Sainte-Beuve in his commentary on Flaubert's Salammbô; it was taken up (perhaps independently) in 1886 by the psychiatrist Krafft-Ebing in his Psychopathia Sexualis which popularized it; it was directly taken up in 1905 by Freud in Three Essays on the Theory of Sexuality which established it definitively.
