Francesco Porro de’ Somenzi was an Italian astronomer and prolific author of textbooks. He is perhaps best known for his reduction of the star catalogue of Giuseppe Piazzi.
Francesco’s parents were Giovanni Porro and Maria Bonali.

In 1885, he was employed as an astronomer at Turin Observatory, where, after the death of director Alessandro Dorna (1825–1887), he was appointed director of the Observatory and professor of astronomy at Turin University.
