19287 Paronelli           Discovered 1996 Feb. 22 by M. Cavagna and A. Testa at Sormano.
Fede Paronelli (1893-1944) held a degree in philosophy and studied astronomy with Camille Flammarion in Paris. During 1931--1942 she was a tireless lecturer at Civico Planetario Hoepli in Milano. During hundreds of conferences she illustrated the beauties of the skies, bridging together science, poetry, music and philosophy.
