Carver has three articles cited in Scifinder, the American Chemical Society's standard journal search engine. Two are patents on inorganic dyes, small variations on existing technology, and one is an article on cultivation of sweet potatoes. Gilbert Nathan Lewis, a chemist of the same generation, and a genuinely great one, whose work is mentioned in every freshman chemistry text (Lewis acids; Lewis structures, etc.), has 81. On the other hand, search google, and you'll find hundreds of hits for Carver, while you'll have to wade through pages of irrelevant google hits to find a biography of Lewis. Carver has a National Park devoted to him. Lewis grew up a few blocks from where I sit, but no one knows exactly where, because the farmhouse is long gone and forgotten. So which one is being ignored on account of his race?
