8155 Battaglini           Discovered 1988 Aug. 17 at Osservatorio San Vittore.
Named in memory of Giuseppe Battaglini (1826-1894), Italian mathematician. University professor of superior geometry at Napoli and Roma, he was founder of the Giornale di Matematiche ad uso degli studenti delle Università Italiane. He introduced Italy to the non-Euclidean geometry of Lobachevskij, and his translations of some of Todhunter's texts were used for many years by Italian university students.
