Named in memory of Ernst Zinner (1886–1970), assistant astronomer (1910–1914) and director (1926–1953) of the Remeis-Sternwarte, Bamberg. In addition to his observational work on variable stars, Zinner was the first professor of astronomy to investigate the history of astronomy in the Middle Ages quantitatively. Giacobini’s {see planet  (1756)} comet 1900 I was rediscovered by Zinner in October 1913 and is now known as P/Giacobini-Zinner, parent of the Draconid meteors. (M 22502) _ _.
