Biography

Della Torre was born in Rome and sources differ on his birth year. His father, Marquis Michele, came from Lavagna but had moved to Genoa. In 1720 Della Torre began his studies at the Clementine College.Шаблон:Sfn Under the guidance of the mathematician Domenico Chelucci (1681–1754), General of the Piarist Order, a wholly new type of teachers and professors was being trained here, who were taught the classics thoroughly, but also acquired a sound knowledge of the sciences, of geography and of history.

Della Torre joined the Somaschi Fathers in 1729, taking his final vows on 30 November 1730. From 1736 he taught mathematics at the Clementine College. In 1738 was appointed to teach mathematics and experimental physics in the archiepiscopal seminary in Naples. In 1743 Charles III of Bourbon appointed him as his personal Librarian, Superintendent of the Stamperia Reale, and Keeper of the Museum of Capodimonte. Della Torre was a member of the Academy of Sciences of Naples. He was also corresponding member of the Academies of Sciences of Paris and Berlin, and of the Royal Society of London.Шаблон:Sfn He was one of the founding members of the Accademia Ercolanese.Шаблон:Sfn

Della Torre was a man of great learning, but his main research fields were microscopy and volcanology. His major contribution was the series of books on the Scienza della natura (Science of Nature) published initially in two volumes (1748-49). The work covers a wide range of scientific subjects in a systematic way and contains many original observations.Шаблон:Sfn

Della Torre documented the Vesuvius eruption of 1751 and spent over twenty years studying the eruptive history of the volcano. The result of his research was published in the Storia e fenomeni del Vesuvio (Naples, 1755), widely considered a milestone in the history of volcanology and translated into French as Histoire et phénomènes du Vésuve (Naples, 1771).

In 1763 Della Torre published a detailed account of the observations he had made with a microscope of his own construction.Шаблон:Sfn Already in 1751 Della Torre had devised a method of forming over a lamp globules of glass which he then placed in cells of brass, adapted to a screw-barrel microscope.Шаблон:Sfn With the aid of these microscope-glasses, he carried out several observations as on the shape of the human blood corpuscles, that caused a stir and, often, disagreement among his contemporaries.Шаблон:Sfn The researches and teaching of Della Torre opened a new field to the Neapolitan naturalists in microscopical investigations.

Legacy

Della Torre is particularly known for his observations of blood corpuscles described in a short publication entitled Praeclarissimo viro abati Noleto, which was printed in 1760. Della Torre wrote letters to a number of scholars, giving them a detailed description of his observations, and sent copies of his essay to others.[1] He also showed his observations to several scholars, who in turn described them to others, as did for example, Raimondo Cocchi (1733-1775) to Felice Fontana (1730-1803). The shape of the red corpuscles was at the time a much-debated topic. Sénac, for instance, believed they had a 'lenticular' form, whereas Haller held the older view that they were 'spherical'. Della Torre denied that they were spherical and described them as tiny membranaceous bags of a ring-like shape, filled with lymph, and pierced in the middle. His observations generated much sensation, skepticism, and controversy. In response, Della Torre refined his arguments and provided longer descriptions of them in what are probably his two most original works as a microscopist: Nuove osservazioni intorno la storia naturale (Naples, 1763) and Nuove osservazioni microscopiche (Naples, 1776).
