12524 Conscience           Discovered 1998 Apr. 25 by E. W. Elst at the European Southern Observatory.
Hendrik Conscience (1812-1883) was a founder of Flemish literature. Although he started writing in French, he soon changed to Flemish. In 1838 he published the historical novel De Leeuw van Vlaanderen ("The Lion of Flanders"), which describes the fourteenth-century battle between the Flemish and French.
