13647 Rey           Discovered 1996 Apr. 20 by E. W. Elst at the European Southern Observatory.
In Amsterdam from 1744 onward, Marc-Michel Rey (1720-1780) was a major figure in the publishing history of the Enlightenment. Manuscripts were smuggled out of France and found their way to Amsterdam, where they were printed and brought back to France clandestinely.
