Francesco Negri
Francesco Negri (18 December 1841 – 21 December 1924) was an Italian photographer known not only as a pictorialist but for his innovative work in photomicroscopy, in the development of the telephoto lens, and for his early experiments in Louis Ducos du Hauron’s techniques of colour photography. His scientific and cultural pursuits included botany and local history: in both fields, his publications remain significant. He served as Mayor of Casale Monferrato.

- 1.Samuel Butler recounts that Cavaliere Negri, at Casale-Monferrato, told me not long since that when he was a child, during the troubles of 1848 and 1849, the King was lunching with his (Cav. Negri’s ) father who had provided the best possible luncheon in honour of his guest. The King said: “I can eat no such luncheon in times like these - give me some garlic.” The garlic being brought, he ate it along with a great hunch of bread, but would touch nothing else.
