Ralph WyckoffDied 3 Nov 1994 at age 97 (born 9 Aug 1897). Ralph (Walter Graystone) Wyckoff was an American scientist, a pioneer in the application of X-ray methods to determine crystal structures and one of the first to use these methods for studying biological substances. He became famous in two areas of structural research: X-ray diffraction and electron microscopy. He developed a new technique of 'metal shadowing' for observation with the electron microscope. A specimen, such as a virus, is placed in a vacuum together with a heated tungsten filament covered with gold. Vaporized gold coated the side of the specimen nearest the filament, leaving a 'shadow' on the far side. This allowed better estimates to be made of their size and shape, as well as revealing details of their structure. |
