Named in honor of Gualberto Mario Iannini (1917– ), Argentinean astronomer who has worked in the field of astrometry for almost 40 years. As a student, Iannini studied the orbit of C/1942 C1 (Whipple-Bernasconi-Kulin). In 1962 he joined the faculty of the School of Mathematics, Astronomy and Physics of the National University of Córdoba and became head of the Department of Astrometry of the Córdoba Observatory, where he finished the reduction of the meridian circle catalogue of the Southern Polar Cap, known as the Córdoba E catalogue.
