11969 Gay-Lussac           Discovered 1994 Aug. 10 by E. W. Elst at the European Southern Observatory.
Joseph-Louis Gay-Lussac (1778-1850) was a French chemist and physicist, one of the founders of meteorology. In 1802 he showed that all gases expand by the same fraction of their volume with temperature. However, he is primarily known for his law stating that "gases combine in very simple proportions".
