Aldo Antonelli (1962 – 2015) (several updates)

G. Aldo Antonelli, professor of philosophy at the University of California, Davis, died unexpectedly earlier this week. Professor Antonelli was known largely for his work in logic. 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. You can learn more about Professor Antonelli at his website. His partner is Elaine Landry, philosopher of mathematics, also in the UC Davis Department.

I will post links to memorial notices as they appear.

UPDATE: Via PHILOS-L, from Curtis Franks (Notre Dame):

Aldo Antonelli, whose work in pure and applied logic and the philosophy of mathematics is well-known to many readers of this list, died suddenly while bicycling with friends in Sacramento yesterday.

Aldo contributed to our understanding of the complexity of the non-well founded sets and of the arithmetical heirarchy with novel aplications of the revision theory of truth. He contributed to the consistency problem for NF and the development of defeasible consequence. In a series of papers he recovered and developed Frege’s unique and overlooked metalogical program. His most recent and possibly deepest work extended the generalized interpretation of quantifiers to the first-order case. He was a dedicated teacher, mentor, and advisor, whose unique pedagogical style will be long remembered.
