GUIDO HORN D'ARTURO (Trieste, 1880-1967)


Graduated in astronomy in Wien and was director of Bologna Observatory since 1920. Besides his scientific activity (among other achievements, the construction of the specchio a tasselli, progenitor of the multiple mirror telescopes) particularly relevant were his efforts to give the library a modern organization, providing a card catalogue and a subject classification, and giving the archives their present organization, both chronological and by subjects. He also contributed to the diffusion of amateur astronomy with his Piccola enciclopedia astronomica (together with Piero Tempesti) and founding the journal COELUM, (1931-1986).
