Dear VSNET partecipants yesterday July 31 prof. Leonida Rosino passed away. This is a most sad day for variable star people and for those who had the privilege to study and to work with him. In all Observatories around the world I had visited I've always been asked about prof. Rosino, his dedication to astronomy and half a century of renowned researches well known everywhere. Leonida Rosino was born in 1915, earned his degree in physics at the University of Bologna in 1938 and from 1953 to 1985 (when he retired) he was the director of the Padua and Asiago Observatories. Under his leadership, the 1.22 m telescope in Asiago (the largest in Europe until late fifties) was first joined by two large Schmidt telescopes and eventually in 1973 by the 1.82 m reflector, still the largest on the Italian national grounds. He was instrumental to establish the first Italian Department of Astronomy at the University of Padua in 1968. One of the most famous Italian astronomer of any times, Leonida Rosino favored research topics have been the globular clusters, variable stars of all kinds, novae and supernovae. Of his undisputed great teaching ability, keen scientific guide and everlasting enthusiasm several generation of Italian astronomers have heartly benefited. At the age of 82 he was still observing at the telescopes and publishing the results of his more recent studies. Leonida Rosino has been also very active in supporting and encouraging amateur astronomers, promoting their access to the professional observing facilities in Asiago and leading regular annual meetings between amateurs and professionals. An asteroid discovered at Asiago and recently numbered has been proposed to by named after prof. Leonida Rosino. Ulisse Munari Padova and Asiago Observatories
