It is with great sadness to announce that Professor Emeritus Hector Fattorini passed away on October 20th, 2025. 

Hector received his bachelor’s degree from the Universidad de Buenos Aires before completing his PhD at NYU in 1965. Hector first joined the UCLA Mathematics Department in 1967 as a Visiting Professor and gradually rose in the ranks to become a full Professor in 1977. After serving 42 years at UCLA, he retired in 2009.

He was known for his research in control theory and differential equations in linear spaces, receiving funding for his research from the National Science Foundation (NSF) for over 20 years. He was also nominated by his students at UCLA for an Innovative Use of Technology Award.

Hector’s colleague and close friend, Professor Emeritus Theodore Gamelin, wrote, “In those turbulent years toward the end of the 1970’s we spent an academic year in England, followed by my two-year chairship and family move to Santa Monica. Hector continued along his distinguished mathematical career trajectory, publishing cumulatively four books and over a hundred papers.”
