Smith (smĭth), Hamilton Othanel. Born 1931.
American microbiologist. He shared a 1978 Nobel Prize for the discovery of restriction enzymes and their application to molecular genetics.
American microbiologist who isolated bacterial enzymes that could split genetic DNA into fragments large enough to retain genetic information but small enough to permit chemical analysis. The existence of these compounds (called restriction enzymes) was earlier predicted by Werner Arber, and their discovery revolutionized genetic engineering. For this work Smith shared the 1978 Nobel Prize for physiology or medicine with Arber and Daniel Nathans.
The Hebrews were not permitted by the Philistines in the days of Samuel to have a smith amongst them, lest they should make them swords and spears (1 Sam. 13:19). Thus the Philistines sought to make their conquest permanent (comp. 2 Kings 24:16).
