19386 Axelcronstedt           Discovered 1998 Feb. 6 by E. W. Elst at the European Southern Observatory.
Axel Frederik Cronstedt (1722-1765), a mining expert and director of mines in central Sweden, discovered the new element nickel in minerals he found in Hälsingland. Using phosphorus salts and the blowpipe technique he qualitatively analyzed colored metallic oxides.
