16765 Agnesi           Discovered 1996 Oct. 16 by P. G. Comba at Prescott.
Maria Gaetana Agnesi (1718-1799) was the first woman in the western world who can properly be called a mathematician. She wrote a treatise on algebra that was widely translated, and in 1750 she was appointed to a professorship at the University of Bologna.
