4036 Whitehouse           Discovered 1987 Feb. 21 by H. Debehogne at the European Southern Observatory.
As a science journalist and particularly as BBC Online's Science Editor David Whitehouse (b. 1956) has had an important influence on science writing for an international public. His Aliens beneath the Ice won a U.K. Glaxo award in 1998, and he received the European Internet Journalist of the Year award in 2002.
