G. Aldo Antonelli (1962 - October 11, 2015) was an Italian-born philosopher and academic.
He grew up in Torino, Italy, where he received an undergraduate degree in philosophy.
After some time, he attended the University of Pittsburgh for a post-graduate degree, obtaining his PhD.
Prior to taking up his position at UC Davis, he also taught for many years at UC Irvine, and held appointments at Pittsburgh, Yale, Stanford, Michigan State, and elsewhere.
His more recent work in philosophy of logic was concerned with applications of generalized quantifier theory and abstraction principles to the foundations of arithmetic in the more general context of Fregean foundations, as well as making contributions to Frege scholarship.
