Descrição:

The U.S. Postal Service marked the resulting development of the world's first computer, ENIAC, and the Army facility that played a key role in its development, on October 8 when it issued a new Computer Technology stamp at Maryland's Aberdeen Proving Ground.

Gerald McKiernan, U.S. Postal Service Vice President of Legislative Affairs, dedicated the stamp October 8 during a 9:30 a.m. ceremony at the Army Research Laboratory's "Top of the Bay Club" (Building 30) at Aberdeen Proving Ground, Md.

Featured speakers included Representative Robert L. Ehrlich Jr. (R-02-MD); Major General Robert D. Shadley, Commander, U.S. Army Ordnance Center and School; and Dr. John W. Lyons, Director, U.S. Army Research Laboratory.

The stamp image is a high-tech graphic design featuring a brain partially covered by small blocks containing parts of circuit boards and binary language. The colorful image was designed by the team of Nancy Skolos and Tom Wedell of Boston.

In recent years, the Postal Service has integrated computer technology into the design and production of its stamps. Virtually every stamp design now is prepared for presentation and production on computers. The majority of stamp designs sent to production are forwarded in the form of a digital electronic file, meaning printers may never even see the original artwork.

The Computer Technology stamp was produced entirely on computer as a composite design consisting of many elements -- some photo-generated, some generated entirely from computer, and an engraving of the brain from a 19th century anatomy plate.

The selection of Aberdeen Proving Ground as the site for the dedication of the Computer Technology stamp marks not only the 50th anniversary of the launching of ENIAC, but AberdeenÕs role in the seven-year development of that first computer.
