The National Academy of Sciences of Italy

Founded in 1782


The National Academy of Sciences of Italy (the "Academy of Forty") was founded in 1782 as the 'Società Italiana' by the mathematician Antonio Mario Lorgna. Some of those who played an important role in the founding of the Society, such as Lorgna, the mathematician Ruggero Boscovich, and the mathematician Gianfrancesco Malfatti, already have biographies in this archive. However, before giving some details of the founding of the Society, let us give some information on those who do not have biographies in our archive.

Although Lorgna was the driving force behind founding the Society, nevertheless four other men played an important role as founder members. Two of these are Boscovich and Malfatti while the other two are Carlo Barletti (1735-1800) and Lazzaro Spallanzani (1729-1799). Barletti, an ordained priest in the Piarists (a Roman Catholic educational order), was the professor of physics at Pavia University. Spallanzani served as professor of logic, metaphysics, and Greek, then as professor of physics at the University of Modena before gaining worldwide recognition as a physiologist while holding a chair at the University of Pavia. These four were Lorgna's friends and they discussed setting up a Society over many years. On 28 June 1766 Lorgna wrote to Malfatti saying that it was important for Italy to have a scientific journal. Over the following ten years discussions went on and by 1776 Lorgna and Malfatti were discussing Lorgna's "idea of forming an Academy for all Italian scholars". Malfatti thought the idea "noble and glorious" but was worried that they wouldn't get deep enough contributions from mathematicians and other scientists. Barletti was also worried that they might not get the highest quality research, but Lorgna, who was confident that the project would succeed, pushed their doubts aside..

On 1 March 1781, Lorgna went ahead with his proposal sending out a circular letter to leading scientists. He proposed that they formed "a body united only by the cement of love of our country and of free natural genius." He emphasised that the new Society would have a journal which would publish contributions rapidly, thus avoiding the delays that Italian scientists encountered by publishing abroad. He also promised that the journal would be printed to the highest quality, and promised to provide personal funds to ensure that these aims were met. [Lorgna had sold his private collection of paintings by leading artists a few months earlier, and it is almost certain that he did so to fund the Society and its journal.] He didn't explicitly state that papers in the journal would be written in Italian, but this was implicit in the circular. Boscovich and others worried that papers written in Italian would not be read by foreign scientists. Boscovich emphasised this in several letters when he wrote, "Italian is unknown to mathematicians in Paris, England and Germany". Lorgna, however, was confident in his proposal and advised all his friends to "stay calm". He published the first part of the 'Memorie', the Society's Memoirs, in 1782 the year the Society was founded in Verona. Lorgna wrote in the Preface to this first part that "the disadvantage of Italy is that its forces are divided" and that it was necessary "to start combining the knowledge and work of many famous separated Italians" in a single association that "was not of any one State but of all of Italy". His Società Italiana, the Society of the XL, would restrict membership to forty top Italian scientists. In addition to the Italian scholars, he proposed that twelve foreign scientists should be elected to the Society (this was later increased to 25). The Society, he wrote, "belongs to the whole of Italy, not just to a single city." Lorgna was the first President of the Società Italiana, holding this role until his death in 1796. Only after his death was the Society renamed the "Italian Society of Sciences known as Society of the XL". The second President was Antonio Cagnoli (see below). It is worth realising that this "Italian Society" was proposed by Lorgna about 100 years before the unification of Italy which took place in 1861. Originally set up in Verona, the Society relocated to Milan, then to Modena, and in 1875, when Rome was declared the capital of Italy, the headquarters of the Society moved there where it remains to this day.

Here is a list of 28 Italian scientists who became members of the Società Italiana, the "Academy of Forty", when it was founded in 1782. The Academy did not have 40 members at this stage.
