21114 Bernson           Discovered 1992 Sept. 2 by E. W. Elst at the European Southern Observatory.
Reysa Bernson (1904-1944) had a passion for science and after an encounter with Flammarion, who inspired her for astronomy, she founded the Astronomical Association of the North. During the 1937 Universal Exposition she directed the Paris planetarium.This led to the foundation of many new planetaria.
