30305 Severi           Discovered 2000 May 1 by P. G. Comba at Prescott.
Francesco Severi (1879-1961), a student of Corrado Segre and later a professor at the University of Rome, wrote more than 400 books and papers on mathematics, history, education and philosophy. He was one of the major exponents of the Italian school of algebraic geometry.
