13097 Lamoraal           Discovered 1993 Jan. 23 by E. W. Elst at the European Southern Observatory.
Lamoraal, Count of Egmont (1522-1568), was a Flemish nobleman. Together with William of Orange and the Count of Hoorne he protested against the Spanish Inquisition. His life, capture and execution were memorialized in Goethe's play Egmont, with music by Beethoven to accompany its first performance in 1810.
