 Giovanni Battista Grassi, professor of Comparative Anatomy at Rome University, showed that human malaria could only be transmitted by Anopheles (Greek anofelís: good-for-nothing) mosquitoes. Grassi along with coworkers Amico Bignami, Giuseppe Bastianelli and Ettore Marchiafava announced at the session of the Accademia dei Lincei on 4 December 1898 that a healthy man in a non-malarial zone had contracted tertian malaria after being bitten by an experimentally infected Anopheles claviger specimen.
