Angelo Secchi, Jesuit and Scientist 

by Ileana Chinnici (INAF-Palermo Astronomical Observatory)

In the second half of the 19th century, astronomy faced an important change that led to the rise of astrophysics. This change was induced by the application of new techniques, especially spectroscopy and photography, in the astronomical field. Father Angelo Secchi was one of the leaders of this change and his studies largely contributed to the development of the rising astrophysics. In this talk, a short biographical profile of Secchi and a survey of his main scientific results (with special attention to his early spectral classification of stars) will be illustrated.
