(10057) L'Obel Main-belt Asteroid
Discovered on 11 February 1988 by E. W. Elst at La Silla.
Matthias de L´Obel (Lobelius, 1538-1616) was a Flemish physician and botanist. In his important work Stirpium adversaria nova (1570), he argued that botany, as well as medicine, must be based on thorough and exact observation.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
