[edit] Biography

Battista Grassi graduated in Medicine from the University of Pavia under professors Camillo Golgi and Giulio Bizzozero Giulio Bizzazzero. After graduation he worked on parasitic worms of medical importance especially the hookworm.in the Department of Comparative Anatomy at Sapienza University in Rome.

From 1878 Grassi worked first at Messina in the Oceanographic Station founded by Nicolaus Kleinenberg and Anton Dohrn where he studied Chaetognatha then at Heidelberg with Karl Gegenbaur and Otto Bütschli.In Heidelberg Grassi married Maria Koenen.

In 1883 he became Professor of Comparative Zoology at the University of Catania, studying cestodes, the life cycle of the European eel (Catania) and the Moray eel (Rome). Also in Catania he began to study entomology and wrote a student text "The Origin and Descent of Myriapods and Insects" in addition to scientific papers. He also began to study Malaria working with Raimondo Feletti on malaria, especially bird malaria.

In 1895 Grassi joined Angelo Celli, Amico Bignami, Giuseppe Bastianelli and Ettore Marchiafava a group working on malaria in districts around Rome as the group’s entomologist. he identified Anopheles claviger as being responsible for the spread of malaria in man.In 1902 Between 1900 and 1902, Grassi, Gustavo Pittaluga and Giovanni Noè made intensive sudies of malaria at Agro Portuense, at Fiumicino, on the Tiber, and on the plain of Capaccio, near Paestum.

In 1902, Grassi abandoned his study of malaria and began work on the sandfly responsible for Leishmaniasis (Phlebotomus papatasii) and on a serious insect pest of the grape vine ( Phylloxera vastatrix ).Endemic malaria returned to Italy during and after the First World War and Grassi resumed his mosquito studies and was working on them when he died.
