Sadism is a term derived from the name of a French aristocrat (Donatien Alphonse-François de Sade), born June 2, 1740 in Paris and who's life has focused mainly around his own pleasure and sex violence. He lived to turn 74, but he spent almost half his life in prisons and insane asylums - 32 years total.
His life is defined as libertine, but most would say that he was indeed evil. His main focus seems to have been abusing young prostitutes and his own employees at his castle in La Coste. His life's major scandals include an affair
with his wife's sister (Anne-Prospere), imprisoning prostitute in his castle, sexually and physically abusing her until she managed to escape by climbing down the window of her second-floor "cell".
De Sade cheating with his wife's sister
By 1763 (23 years of age) he already had police survelling his actions and his mother-in-law had obtained a lettre de cachet against him, a definitive (with no chance of appeal) letter signed by the king himself and by one minister through. After (non-lethal) poisoning and sodomizing several prostitutes with his servant, they were sentenced in absentia, but managed to leave to Italy, taking his wife's sister along and beginning an affair with her.
After being incarcerated, he reunited with his wife, who became an accomplice to all his sexual abuses, which included his young staff at Lacoste. He spent his life running between France and Italy, continuing his sexual abuses and sodomizing everything in his path, and escaped death in 1777, when the father of one young abused servants attempted to shoot him, but the gun misfired.
Prison and divorce
He was tricked into visiting his ill mother, whom was already dead, and was imprisoned, managed to escape again, but got caught soon after. His death sentence was revoked, but the letter of cachet issued at his mother-in-law request got him imprisoned. In 1790 he was released due to the abolishment of the instrument lettre de cachet.
His wife obtained divorce, he then met Marie-Constance Quesnet (former actress, mother of one, abandoned by husband) with who he spent the rest of his life. At this time he was already morbidly obese, managed to obtain official positions, but he was almost guillotined for an
administrative error. He was arrested at Napoleon Bonaparte's order for writing Justine and Juliette (anonymously), incarcerated without trial in Sainte-Pélagie, but transferred to the rough Bicêtre fortress for trying to seduce young inmates.
Incest with a 13 year old at 70
His family managed to transfer him to an asylum at Charenton, where his wife joined him. Later on, after being in solitary confinement and then released, he began an affair with 13 years old Madeleine Leclerc, which lasted for 4 years, until his death.
His work includes Les 120 Journees de Sodome, Incest, The Crimes of Love (I-V).
