70745 Aleserpieri           Discovered 1999 Nov. 9 by V. Goretti at Pianoro.
Italian scientist Alessandro Serpieri (1823-1885) was a teacher of mathematics and physics. As an astronomer, he determined the Perseid radiant and studied the solar eclipse of 1870 Dec. 22. He also analyzed the Italian earthquakes of 1872 and 1875.
