'''Henri Gouraud''' (born 1944) is a French [[computer scientist]]. He is the [[inventor]] of [[Gouraud shading]] used in [[computer graphics]]. He is the great-nephew of general [[Henri Gouraud (soldier)|Henri Gouraud]].

During 1964–1967, he studied at [[École Centrale Paris]]. He received his Ph.D. from the [[University of Utah College of Engineering]] in 1971, working with [[David C. Evans (computer scientist)|Dave Evans]] and [[Ivan Sutherland]], with his dissertation titled ''[http://portal.acm.org/citation.cfm?id=905323&dl=ACM&coll=portal Computer Display of Curved Surfaces]''.<ref>{{cite web |last1=Dalbera |first1=Stéphane |title=Henri Gouraud, the best-known of the little-known |url=https://www.linkedin.com/pulse/henri-gouraud-best-known-little-known-stéphane-dalbera-1sawf/?trackingId=IqJovx9euwfZKd6gXpRQXQ%3D%3D}}</ref>

In 1971, Gouraud made the first [[computer graphics]] [[geometry]] [[digitization|capture]] and representation of a human face in [[wire-frame model]], and applied his [[shader]] to produce the famous human face images showing the effect of his shading, which were done using his wife Sylvie Gouraud as the model.<ref>{{cite web|title=Images de synthèse : palme de la longévité pour l'ombrage de Gouraud|date=14 September 2008 |url=http://interstices.info/jcms/c_25256/images-de-synthese-palme-de-la-longevite-pour-lombrage-de-gouraud}}</ref>
