LIEBREICH, lē'brīK, Oskar (1839—). A German pharmacologist. He was born at Königsberg, studied chemistry under Fresenius in Wiesbaden and medicine in Königsberg, Tübingen, and Berlin, and in the last-mentioned university became assistant in 1867, professor of therapeutics in 1868, and director of the pharmacological institute in 1872. He introduced the method of phaneroscopic illumination for the study of lupus; showed the value of cantharidin in tuberculosis, of mercuric formamide and of lanolin in syphilis, of butylchloral hydrate and of ethylene chloride as anæsthetics, and of chloral hydrate as a soporific; and in 1865 gave the name protagon to a proximate principle discovered in the brain and in blood-corpuscles. Liebreich edited the Therapeutische Monatshefte (1887 sqq.) and the Encyklopädie der Therapie (1895 sqq.), and with Langgaard published a Kompendium der Arzneiverordnung (5th ed. 1902).
