(Born: 1739; Died: 1825) Italian mathematician & naturalist.

Pini was a member of the Order of the Barnabites, and was employed as a professor of natural history at the University of Milan. He wrote many works founded on the natural sciences. His Introduzione allo Studio della Storia Naturale (Milano, 1773; [10], 13-165 p.) contains a history and bibliography of these sciences.
