Last month, the U.S. Postal Service (USPS) prompted a 13 November Random Sample naming a group of scientists whose faces were appearing, USPS said, on stamps belonging to its Black Heritage Series. Among them: chemist Percy Lavon Julian; George Washington Carver; physician Charles R. Drew; astronomer and mathematician Benjamin Banneker; and inventor Jan Matzeliger. Science readers knew better. Two of the quintet appeared years ago: a stamp bearing Carver's picture was issued in 1948, and Drew appeared in the Great Americans Series in 1981.
