69870 Fizeau           Discovered 1998 Sept. 20 by E. W. Elst at the European Southern Observatory.
French physicist Hyppolite Fizeau (1819-1896) improved photographic processes. In a laboratory experiment with Foucault in 1849, he made an independent determination of the speed of light. Using the phenomenon of light interference, he measured successfully the dilations of crystals.
