Il s'agit de rares tirés à part de l'Académie des Sciences de Turin, renfermant deux études du mathématicien, ingénieur militaire et homme politique né en Savoie, Luigi Federico Menabrea [Chambéry, 1809 - Saint-Cassin, 1896]. "Menabrea is known to scientists as one of the most important men in the development of energy methods in the theory of elasticity and structures, and to others as a distinguished general and statesman, each group being generally little aware of Menabrea's accomplishments in the other fields. Indeed, it is remarkable that he was able to make significant contributions in both types of activities (?) Menabrea's place in the history of Italy is assured ; his role in the introduction of concepts of work and energy into analytical mechanics and engineering has been overshadowed by the greater fame of Castigliano. In the United States, for example, Menabrea is hardly mentioned, although in Continental and particularly Italian textbooks the correct distinction of Menabrea's and Castigliano's theorems is generally made. Menabrea's methods placed these concepts for the first time very clearly before the engineering profession and thus started the essential work of education which was completed by Castigliano". Cf.

First edition. THE FIRST COMPUTER PROGRAMMES. First edition, journal issue, of Menabrea's account of the only public presentation that Babbage ever made concerning the design and operation of the Analytical Engine. "This was the first published account of Charles Babbage's Analytical Engine and the first account of its logical design, including the first examples of computer programs ever published. As is well known, Babbage's conception and design of his Analytical Engine-the first general purpose programmable digital computer-were so far ahead of the imagination of his mathematical and scientific colleagues that few expressed much curiosity regarding it. Babbage first conceived the Analytical Engine in 1834. This general-purpose mechanical machine-never completely constructed-embodied in its design most of the features of the general-purpose programmable digital computer. In its conception and design Babbage incorporated ideas and names from the textile industry, including data and program input, output, and storage on punched cards similar to those used in Jacquard looms, a central processing unit called the 'mill,' and memory called the 'store.' In 1840 Babbage traveled to Turin to make a presentation on the Analytical Engine. Babbage's talk, complete with charts, drawings, models, and mechanical notations, emphasized the Engine's signal feature: its ability to guide its own operations-what we call conditional branching. In attendance at Babbage's lecture was the young Italian mathematician Luigi Federico Menabrea (1809-1896), who prepared from his notes an account of the principles of the Analytical Engine. Reflecting a lack of urgency regarding radical innovation unimaginable to us today, Menabrea did not get around to publishing his paper until two years after Babbage made his presentation, and when he did so he published it in French in a Swiss journal [offered here]. Shortly after Menabrea's paper appeared Babbage was refused government funding for construction of the machine" (). "In keeping with the more general nature and immaterial status of the Analytical Engine, Menabrea's account dealt little with mechanical details. Instead he described the functional organization and mathematical operation of this more flexible and powerful invention. To illustrate its capabilities, he presented several charts or tables of the steps through which the machine would be directed to go in performing calculations and finding numerical solutions to algebraic equations. These steps were the instructions the engine's operator would punch in coded form on cards to be fed into the machine; hence, the charts constituted the first computer programs [emphasis ours]. Menabrea's charts were taken from those Babbage brought to Torino to illustrate his talks there" (Stein, Ada: A Life and a Legacy, p. 92). ABPC/RBH list only the OOC copy (Christie's, 2005). In 1828, during his grand tour of Europe, Babbage had suggested a meeting of Italian scientists to the Grand Duke of Tuscany. On his return to England Babbage corresponded with the Duke, sending specimens of British manufactures and receiving on one occasion from the Duke a thermometer from the time of Galileo. In 1839 Babbage was invited to attend a meeting of Italian scientists at Pisa, but he was not ready and declined. "In 1840 a similar meeting was arranged in Turin. By then Babbage did feel ready, and accepted the invitation from [Giovanni] Plana (1781-1864) to present the Analytical Engine before the assembled philosophers of Italy . In the middle of August 1840, Babbage left England . "Babbage had persuaded his friend Professor MacCullagh of Dublin to abandon a climbing trip in the Tyrol to join him at the Turin meeting. There in Babbage's apartments for several mornings Babbage met Plana, Menabrea, Mosotti, MacCullagh, Plantamour, and other mathematicians and engineers of Italy. Babbage had taken with him drawings, models and sheets of his mechanical notations to help explain the principles and mode of operation of the Analytical Engine. The discussions in Turin were the only public presentation before a group of competent scientists during Babbage's lifetime of those extraordinary forebears of the modern digital computer. It is an eternal disgrace that no comparable opportunity was ever offered to Babbage in his own country . "The problems of understanding the principles of the Analytical Engines were by no means straightforward even for the assembly of formidable scientific talents which gathered in Babbage's apartments in Turin. The difficulty lay not as much in detail but rather in the basic concepts. Those men would certainly have been familiar with the use of punched cards in the Jacquard loom, and it may reasonably be assumed that the models would have been sufficient to explain the mechanical operation in so far as Babbage deemed necessary. Mosotti, for example, admitted the power of the mechanism to handle the relations of arithmetic, and even of algebraic relations, but he had great difficulty in comprehending how a machine could handle general conditional operations: that is to say what the machine does if its course of action must be determined by results arising from its own previous calculations. By a series of particular examples, Babbage gradually led his audience to understand and accept the general principles of his engine. In particular, he explained how the machine could, as a result of its own calculations, advance or back the operation cards, which controlled the sequence of operations of the Engine, by any required number of steps. This was perhaps the crucial point: only one example of conditional operations within the Engine, it was a big step in the direction of the stored program, so familiar today to the tens of millions of people who use electronic computers. "In explaining the Engines Babbage was forced to put his thoughts into ordinary language; and, as discussion proceeded his own ideas crystallized and developed. At first P.
