Giuliani at Sormano. Federico Ernesto Delpino (1946-2007), an astronomer at the Bologna Observatory, began his scientific career by studying x-ray and \gamma -ray sources and the microwave cosmic background. He contributed to the creation of the electronic network at the University of Bologna and participated in astronomical popularization.
