17435 di Giovanni           Discovered 1989 Sept. 26 by E. W. Elst at the European Southern Observatory.
Alessio di Giovanni (1872-1946) was a Sicilian poet who wrote about humble, realistic issues. Well known for Lu fattu di Bissana ("The Bissana Incident", 1900) and In la dispensa di la surfara ("In the storehouse of the sulfur mine", 1910), he devoted his life to poetic inspiration.
