After graduating in physics from the
University of Padua in 1938, he devoted himself to astronomy, becoming an assistant to Giovanni Silva. His scientific training was completed by a two-year stay at the
Yerkes Observatory of the
University of Chicago, from 1948 to 1950. He obtained a degree in astronomy in 1948; from 1939 to 1953 he was first assistant and then professor in charge of
spectroscopy at the
University of Bologna, at the chair of Francesco Zagar. He became full professor of astronomy at the
University of Cagliari in 1953, then moved to the University of Bologna in 1954 and, in 1956, to the University of Padua, where he remained until his appointment as professor emeritus. In 1956 he became the director of the
Asiago Astrophysical Observatory. Author of over 250 scientific publications, he made original contributions to the study of
variable stars,
globular clusters, and the physics of
novae and supernovae, which made him internationally famous. He discovered 23 supernovae (five of them together with other scientists); he also discovered the
cataclysmic variable AL Comae Berenices on 16 November 1961. Leonida Rosino was a member of many national and international scientific societies including the
Accademia dei Lincei and the
Veneto Institute of Sciences, Letters and Arts. The Asiago
Cima Ekar Observing Station was named in his memory on 15 November 1997. In the station there is a plaque with his image, bearing the inscription "Leonida Rosino 1915 - 1997 Unparalleled master, creator and creator of this astronomical station - November 15, 1997". ==Major works==
