18396 Nellysachs           Discovered 1992 Sept. 21 by F. Borngen and L. D. Schmadel at Tautenburg.
Lyric poet Nelly Sachs (1891-1970), coming from a Jewish family in Berlin, escaped abroad in 1940 and became a Swedish citizen. In her work she grappled with the fate of the Jewish people. She shared the Nobel prize for literature in 1965. The name was suggested by the first discoverer.
