Jules Louis Dupré (April 5, 1811 – October 6, 1889) was a French painter, one of the chief members of the Barbizon school of landscape painters. If Corot stands for the lyric and Rousseau for the epic aspect of the poetry of nature, Dupré is the exponent of its tragic and dramatic aspects.

Henri (Hendrik) Conscience (3 December 1812 – 10 September 1883) was a Belgian author. He is considered the pioneer of Dutch-language literature in Flanders, writing at a time when Belgium was dominated by the French language among the upper classes, in literature and government. Conscience fought as a Belgian revolutionary in 1830 and was a notable writer in the Romanticist style popular in the early 19th century. He is best known for his romantic nationalist novel, The Lion of Flanders (1838), inspired by the victory of a Flemish peasant militia over French knights at the 1302 Battle of the Golden Spurs during the Franco-Flemish War.
Over the course of his career, he published over 100 novels and novellas and achieved considerable popularity. After his death, with the decline of romanticism, his works became less fashionable but are still considered as classics of Flemish literature.

Casimir-Joseph Davaine (19 March 1812 – 14 October 1882) was a French physician known for his work in the field of microbiology. He was a native of Saint-Amand-les-Eaux, department of Nord.
In 1850, Davaine along with French pathologist Pierre François Olive Rayer, discovered a certain microorganism in the blood of diseased and dying sheep. In the diseased blood, Rayer and Davaine observed the bacillus that is known today as Bacillus anthracis, the causative bacterium of anthrax. Soon afterwards, Rayer published a description of the bacillus in a paper titled, Inoculation du sang de rate (1850).In 1863, Davaine demonstrated that the bacillus could be directly transmitted from one animal to another. He was able to identify the causative organism, but was unaware of its true etiology. Later on, German microbiologist Robert Koch investigated the etiology of Bacillus anthracis, and discovered its ability to produce "resting spores" that could stay alive in the soil for a long period of time to serve as a future source of infection.Casimir Davaine is also credited for pioneer work in the study of sepsis (blood poisoning).
