This spreadsheet shows the two souls of Giovanni Ansaldo: the artistic one and the mathematical one. The founder of Gio. Ansaldo & C. studied the art of drawing, but later embarked on a university career, graduating at the age of 21 in Civil Engineering and, the following year, in hydraulic engineering. In love with numbers and science, he obtained prestigious positions: in 1847 he was called to the chair of descriptive geometry in the faculty of philosophy and arts of the University of Genoa and, subsequently, he was entrusted with the chair of mechanics applied to the arts in the evening technical school by himself established. The content of the sheet is most likely a discussion of Descartes' folium, in preparation for some academic lecture. At the time it was already well known and therefore no longer a cause for research. Furthermore, the pencil sketch of an angel, in addition to showing the artist's artistic flair, suggests that the sheet was probably for personal use.
In the Foundation there is the Giovanni Ansaldo Fund containing the academic qualifications, notes and study texts of scientific subjects and university lectures.
