(21114) Bernson Main-belt Asteroid
Discovered on 2 September 1992 by E. W. Elst at La Silla.
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.Naming citation (WGSBN Bull. 3, #13, 13), IAU / Minor Planet Center, via NASA/JPL
