Adriano Garsia

Adriano Mario Garsia (1928 to 2024) was a Tunisian-born Italian American mathematician whose work ran through analysis, combinatorics, representation theory and algebraic geometry. Born in Tunis, he moved to Rome in 1946, studied under Charles Loewner, and spent 57 years on the faculty of the University of California, San Diego, as a founding member of its mathematics department, retiring in 2013. He is known for the Garsia-Wachs algorithm for optimal binary search trees, published in 1977 with his student Michelle Wachs, and for formulating with Mark Haiman the n! conjecture. He wrote books on almost everywhere convergence, martingale inequalities and enumerative combinatorics, supervised 36 students, and became a fellow of the American Mathematical Society in 2012.
