Leonard Misonne (1870 – 1943) was a Belgian photographer.
Misonne was born on July 1, 1870, in Gilly, Belgium, his lifelong home.
Misonne was the seventh son of Louis Misonne, lawyer and industrialist, and Adele Pirmez. He studied mining engineering at the Catholic University of Louvain, but never worked as an engineer. Still a student, he became interested in music, painting and from 1891, in photography which he started to work on exclusively from 1896.
Misonne made several trips to Switzerland, Germany and France. He made himself known with his retouched lighting effects. "The subject is nothing, light is everything," he said. Misonne was known for his sense of creating an atmosphere, but his approach is labeled from an artistic point of view as conservative and sentimental.
His blurred effects, like the impressionist's approach, earned him the nickname of the "Corot of photography"
Misonne first worked mainly with the process of photography obtained from a suspension of silver bromide in gelatin that he learned in 1910 in Paris from the famous photographer Constant Puyo. Then he became an internationally renowned leader in Pictorialism and a well-known figure in avant-garde circles. Most of his shots were taken in Belgium and the Netherlands; they are mainly landscapes, sometimes scenes of beaches and views of Ghent and Antwerp.
Misonne suffered from a severe form of asthma and died from it in 1943, in Gilly, Belgium.
