masochism (n.)

"sexual pleasure in being hurt or abused," 1892, from German Masochismus, coined 1883 by German neurologist Richard von Krafft-Ebing (1840-1902), from name of Leopold von Sacher-Masoch (1836-1895), Austrian utopian socialist novelist who enshrined his submissive sexuality in "Venus in Furs" (1869, German title "Venus im Pelz").

Sacher-Masoch's parents merged their name when they married; von Masoch is his mother's surname. She was said to be from the Ukrainian aristocracy, and Masoch may represent a Germanized form of a Slavic name, probably a place-name.
