Charles Loyson (1827-1912) with wife and son

François-Frédéric Boissonnas, known as Fred Boissonnas, was a Swiss photographer from Geneva. His work is considered crucial for the development of photography in Greece, and its use in favourably publicising the country's expansionist ambitions, during the early 20th century. Boissonnas constitutes a central figure in the transition from 19th century approaches to a more contemporary photography of antiquities.
