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.
