Bright but cocky, Greenewalt finished Philadelphia's William Penn Charter School among the top ten of his class. In the 1918 class yearbook was written: "Who is the brightest? Evans.* Who thinks he is? Greenewalt." Greenewalt went off to M.I.T. with no clear notion of what he wanted to be, settled on chemical engineering, but was better known for his eye for pretty girls than for his scholarship. With a B.S. from M.I.T. Greenewalt got a $120-a-month chemist's job at Du Pont, but was still aimless about his future. While watching vats on a graveyard...
Hobby Lobby. The Greenewalts live in a 15-room rambling stone hilltop house 7½ miles outside Wilmington with their children, Nancy, 22, David, 20, Crawford Jr., 13. Greenewalt, who used to play clarinet, cello and the piano, now likes to tootle on the basset horn. His restless mind ranges rapidly from hobby to hobby. To make model steam and gasoline engines he transformed one big downstairs room into a machine shop. He also grows orchids. To show the entire process of blooming, he once rigged up an electrically-controlled movie camera to photograph plants at 15-minute intervals...
...fact that Greenewalt married the boss's daughter did not hurt him at Du Pont, but he still had to make his own way. He became an expert in high-pressure synthesis, a new field which opened the door to all kinds of chemical processes, (e.g., urea, long-chain alcohols), won 18 patents, most of them used by Du Pont. It was Greenewalt's work on nylon-the biggest treasure yet turned up in Du Pont test tubes-which put him far up on the skimmer chart. Du Pont's brilliant scientist, Dr. Wallace Carothers, first materialized...
...Frontiers. The Du Pont revolution is still growing. President Greenewalt himself has been testing a new suit, made of Du Pont's newest synthetic fiber, Dacron. It looks and feels like wool, but outwears it, costs only half as much, is washable and mothproof-and is virtually wrinkleproof. Says Greenewalt: "The only way you can get the crease out is with an iron...
...Wilmington wizards are constantly performing. In three years they have popped out everything from a sulphur-coated grass seed which grows greener grass, to a chemical called Erifron, which makes cotton and rayon flame resistant. They have also produced a revolutionary new insulating material called Teflon. Out of Greenewalt's old specialty, high-pressure synthesis, came some long-chain alcohols which long seemed useless, but have now made Du Pont a prime supplier of raw materials for soapless soaps (detergents). In a pilot plant at Wilmington, Du Pont is turning out titanium metal-as light as aluminum...
