Elizabeth Beckley (c. 1846–1927) was the first observer with the new photoheliograph at the Kew Observatory, London. She began working there in the 1860s, as a teenager, and continued for over a decade, using the labor-intensive ‘wet collodion’ process in solar photography for the first time.Naming citation (WGSBN Bull. 2, #8, 10), IAU / Minor Planet Center, via NASA/JPL
