François-Frédéric Boissonnas (18 June 1858 – 17 October 1946), known as Fred Boissonnas, was a Swiss photographer from Geneva. Boissonnas constitutes a central figure in the transition from 19th century approaches to a more contemporary photography of antiquities. Frédéric ran the family studio from 1887 to 1920. In 1901, he went into partnership with André Taponier to create a studio in Paris, and with M. Neumayer in Reims.
