Adriano Mario Garsia (20 August 1928 – 6 October 2024[1]) was a Tunisian-born Italian American mathematician who worked in analysis, combinatorics, representation theory, and algebraic geometry.
He was a student of Charles Loewner and published work on representation theory, symmetric functions, and algebraic combinatorics.
He is also the namesake of the Garsia–Wachs algorithm for optimal binary search trees, which he published with his student Michelle L. Wachs in 1977.
[2] Born to Italian Tunisians in Tunis on 20 August 1928, Garsia moved to Rome in 1946.
At his 90 Birthday Conference in 2019, it was notable that he was the oldest principal investigator of a grant from the National Science Foundation in the country.
