Frederic Eugene Ives

Died 27 May 1937 at age 81 (born 17 Feb 1856).American photographer and inventor of the halftone process, a method of reproducing photographs on a printing press. Prior to this process, photos and illustrations were reproduced from hand-engraved plates. In this way printers could reproduce line drawings, but not the shades of gray in a photograph because printing presses cannot print gray - only black and white. Ives invented a screen that would convert a photograph into a pattern of tiny dots. Large dots form where the image is dark, and tiny dots where the image is light, thus giving the illusion of shades of gray. In 1881, he was the first to make a three-colour print from halftone blocks. Further inventions in photography and colour printing yielded 70 patents.(Image: 1996 U.S. postage stamp.)

A housewife with three young children was getting dinner ready when the phone rang. The six-year-old picked it up and said, "Hi, Daddy!" and she began telling him about her day.
She then passed the phone to her brother and sister as was the custom whenever Daddy called from work.
When it was finally the wife's turn to talk she took the receiver and said, "Hi, honey."
"Thank goodness, lady," the voice on the other end replied. "I just called to tell you that the wallpaper you ordered is here!"
