14327 Lemke           Discovered 1980 Mar. 16 by C.-I. Lagerkvist at the European Southern Observatory, Chile.
Dietrich Lemke (b. 1939), the principal investigator of the ISOPHOT instrument on board ESA's Infrared Space Observatory, has encouraged the study of minor planets in the thermal infrared, resulting in their being established as a new class of far-infrared/submillimeter calibrators.
