13044 Wannes           Discovered 1990 Aug. 16 by E. W. Elst at the European Southern Observatory.
Wannes van de Velde (1937-2008) was a Flemish singer, musician and poet. He sang his rebellious songs in the local dialect of Antwerp, a choice that was not always appreciateid by the city's intelligentia. His song Ik wil deze nacht in de straten verdwalen ("This night I want to stray through the city") became popular.
