sadisme

from the name of the marquis de sade, known for his libertine writings evoking the pleasure of harming others. the term is listed in the posthumous 1834 edition of boiste's universal dictionary of the french language; it is reused with 'sadique' in 1862 by sainte-beuve in his commentary on flaubert's salammbô; it is taken up (perhaps independently) in 1886 by the psychiatrist krafft-ebing in his psychopathia sexualis which popularizes it; it is directly taken up in 1905 by freud in three essays on the theory of sexuality which definitively establishes it.
