1835, from German Kreosot, coined 1832 by its discoverer, German-born natural philosopher Carl Ludwig, Baron Reichenbach (1788-1869), from Greek kreo-, comb. form of kreas "flesh" (see raw) + soter "preserver," from soizein "save, preserve" (perhaps from PIE root *teue- "to swell"). So called because it was used as an antiseptic.
