Named for the German architect Gottfried Semper (1803–1873). On the recommendation of Schinkel {see planet  (5297)} he became a professor at Dresden Academy. He built the Dresden {see planet  (3053)} museum and synagogue, as well as the most famous “Semper Operahouse”, destroyed during World War II but rebuilt. Semper also worked in Zürich and Wien, where many buildings designed by him — including the Zürich Observatory — are still in use. (M 26766) _ _.
