The prized moon rock that was presented to the Dutch Prime Minister Willem Drees in 1969 by United States Ambassador J. William Middendorf during a goodwill tour by three of the Apollo astronauts turned out to be a piece of petrified wood.
J. William Middendorf, who was the chairman of the Republican National Committee from 1965 until 1969, was sent as an ambassador by president Richard Nixon. Middendorf said that the State Department had given him the stone.
In 2006 a space expert expressed doubts about the "moon rock." The Dutch National Museum intends to continue displaying it with the story of its interesting history.
