21059 Penderecki           Discovered 1991 Apr. 9 by F. Borngen at Tautenburg.
Krzysztof Penderecki (b. 1933), a Polish professor of composition at several conservatories, turned after his first experiments to plainer and more comprehensible compositions. He is a very essential representative of moderate modernity. His Dies irae and other sacred works attained worldwide success.
