José Luis Sérsic (6 May 1933 – 19 July 1993) was an Argentine astronomer best known for his contributions to extragalactic astronomy. He is the namesake of the Sérsic profile, which he published in 1963.

Biography

Early life and education

José Luis Sérsic was born in Bella Vista, Corrientes, Argentina on May 6, 1933[1].

Career

In 1956, Sérsic completed his doctorate in astronomy at the National University of La Plata on celestial mechanics. His dissertation, titled "Applications of a certain type of canonical transformations to celestial mechanics", was completed under the supervision of Reynaldo Cesco[2]. He moved to the National Observatory of Cordoba in 1957. Sérsic was a founding member of the Argentine Astronomical Association in 1958.

In 1963, Sérsic published the mathematical function that is now known as the Sérsic profile[3].
