Giuliani and P. Chiavenna at Sormano. Emilio Molinari (b. 1963), developed his astronomical career in Brera Observatory, Milan, beginning with the study of distant clusters of galaxies then shifting to technology group. He now serves as director of the Telescopio Nazionale Galileo and Rapid Eye Mount observatories.
