Jesuit astronomer. Born in 1818 in Reggio Emilia, Italy; died on February 26, 1878 in Rome, Italy. He came to America in 1848 and was professor at Georgetown University. The next year he became director of the observatory in the Roman College. In astronomy the sun was the chief object of his study. He laid the foundations of the unique Sun Records, discovered the "flash spectrum," invented new instruments for the study of the fixed stars, and discovered the five Secchi types of stars. In meteorology he was a disciple of Maury, and invented the "Meteorograph." He acquired fame as a physicist by his Sulla unità delle forze fisiche. After 1870 he remained firm in his allegiance to the pope.
