10350 Spallanzani           Discovered 1992 July 26 by E. W. Elst at the European Southern Observatory.
Italian biologist Lazzaro Spallanzani (1729-1799) was known for his research on the spontaneous generation of cellular life. He also proved that microbes come from the air, paving the way for Pasteur. His masterpiece was Dissertationi de fisica animale e vegetale (1780), an interpretation of the process of digestion.
