Annibale de Gasparis, the sublime calculator of Parthenope's sky

Abstract

Annibale de Gasparis was a mathematician and astronomer, director of the Capodimonte Observatory, and senator of the Kingdom of Italy, especially famous for the discoveries of 9 asteroids, the greatest number of discoveries made in Italy
throughout the 19th century. His correspondence is scattered in some Italian and European archives and consists of more than 500 letters exchanged with over 120 correspondents, like Herschel, Le Verrier, Arago, Secchi, and Sella. De Gasparis
played a relevant role in the mathematical developments of celestial mechanics, as witnessed by Hermite’s letter. Furthermore, his scientific reputation went beyond the boundaries of astronomy, becoming famous in popular magazines and the protagonist of verses and books, popularizing the scientific value of his discoveries. Reconstructing the atmosphere of those years, the letters give a clear view of de Gasparis’ relationships and scientific interests and present a cross-section of the human kindness of the astronomer.
