Jules Desneux (20 April 1885 – 4 January 1962) was a French-Belgian entomologist, dermatologist, art historian, and numismatist.
He studied humanities at the Athenee royal d'Ixelles from 1896 and at the age of 17 met Auguste Lameere and learned about termites and examined some collections from Africa that resulted in a paper in 1902.
[1][2] Desneux collected coins and in 1930 he described ancient Greek coinage and was a member of the numismatics society, serving as its president from 1955 to 1957 and again from 1958 to 1961.
[3] He was also interested in art investigation and used infra-red photography to examine hidden drawings under the paintings by Jan van Eyck.
He had diagnosed the condition from a pre-restoration photograph as a plaque keratosique, a potential malignant squamous cell carcinoma for which dermatologist would have prescribed a diagnostic biopsy.
