“Excellent biography […] Historians of science, whatever their national origin, should become familiar with the achievements of Father Secchi.”Naomi Pasachoff, Williams College. In: Metascience, Vol. 29, No. 1 (March 2020), pp. 77–80 (2020).“[This] will undoubtedly be the standard work on this remarkable Jesuit astronomer.”Wayne Orchiston, National Astronomical Research Institute of Thailand, and Centre for Astrophysics, University of Southern Queensland. In: Journal of Astronomical History and Heritage, Vol. 23, No. 1 (April 2020), pp. 227–228.“This excellent book not only presents Secchi’s scientific contributions and his personality but also situates him in the fascinating mix of science, politics and society of the Italian late nineteenth century.” Augustín Udías, Universidad Complutense, Madrid. In: Journal for the History of Astronomy, Vol. 52, No. 1 (2021), pp. 111–112. “Chinnici’s excellent biography gives us a thorough and strongly felt portrait of Secchi’s personality and work, especially, through his letters and writings. This is an important work for the history of astronomy and astrophysics in Italy; more generally, it aids the historical exploration of Jesuit contributions to science and the wider relationship between science and religion.”Agustín Udías, S.J., Universidad Complutense, Madrid. In: Archivum Historicum Societatis Iesu, Vol. 88, fasc. 176 (2019-II), pp. 611–613.
