27710 Henseling           Discovered 1988 Sept. 7 by F. Borngen at Tautenburg.
German teacher and author Robert Henseling (1883-1964) wrote numerous popular astronomical books and helped many to understand the wonders of the cosmos. He founded the Volkssternwarte in Stuttgart and, in 1921, the journal Die Sterne. One of his lasting cultural historical effects is his analysis of astrology.
