In 1872, then a professor at Liceo Gioberti, Luigi Bellardi began I molluschi dei terreni terziari del Piemonte della Liguria, a work on molluscs of the Middle and Early Tertiary in the Mediterranean basin. In 1888 he published the five parts dealing with Cephalopoda, Pteropoda and the first families of Gastropoda. In 1889 his student Prof. Federico Sacco (1864–1948) took over this work and published 25 more sections partly based on Bellardi’s work on this species-rich fossil group.
A list of his publications can be found at the database WoRMS.[1]
