There was an elderly widow who lived in a large mansion. She was feeling generous when it came to Thanksgiving, so she called up the local military base, and asked to speak with the lieutenant.
"Please send up four nice young men to eat dinner here on Thanksgiving, but please, don't send any Jews. Please, no Jews."
The lieutenant replied, "No problem ma'am, and I am sure I speak for the army when I say we all appreciate your kindness."
Well, Thanksgiving rolled around, and the widow went to answer the door when it rang. She was surprised to see four black recruits. "But... But... There must be some mistake," she stammered.
One of them replied, "No ma'am, Lieutenant Goldstein doesn't make mistakes."

Ralph Wyckoff

Died 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.
