Named in memory of Alfred Wilke (1893–1972), an optician of the highest rank, who constructed a workshop and observatory at Falkensee, near Berlin. Right up to his death he made optics by the thousands for astronomical institutes and popular and school observatories, as well as for numerous amateurs. Among his works are the 0.50-m Schmidt cameras for both Sonneberg and Babelsberg, the 0.70-m Cassegrain reflector for Potsdam and the 0.70-m and 0.54-m Cassegrains for Babelsberg. (M 15261) _ _.
