A student of the famous landscape painter Jean-Victor Bertin, Jules Defer entered the Ecole des Beaux-Arts in Paris in 1824. From 1829, he presented the competition for the Grand Prix de Rome in the "section Historical Landscape". He settled on the French Riviera shortly after the attachment of Savoy and the county of Nice (1860), first in Monaco, then in Nice around 1863. He devoted himself all his life to the production of paintings brushed on the motif in the Nice region, generally in small formats, imbued with a beautiful sensitivity and highly sought after by collectors. By his precise gesture and his palette of colors, the painter Jules Defer succeeds in depicting with precision and on the spot the Mediterranean vegetation, its atmosphere and its play of light.
