5927 Krogh           Discovered 1938 Apr. 19 by W. Dieckvoss at Bergedorf.
American mathematician Fred T. Krogh (b. 1937) developed the accurate, flexible and fast numerical integration algorithm used to track and navigate NASA interplanetary spacecraft since the 1970s. His work is at the core of JPL planetary, asteroid and comet orbit solutions and ephemerides.
