80135 Zanzanini           Discovered 1999 Oct. 7 by S. Sposetti at Gnosca.
Giuseppe Zan Zanini (1794-1869) lived in Val Bavona and Val Foiòi in Ticino, Switzerland. His history is a symbol of the hard life and fragile existence supported by the valley inhabitants of Ticino in 1800. The name was suggested by G. and C. Brenna.
