Louis Pasteur

Félix Vallotton's caricature of the renowned microbiologist Louis Pasteur employs the elongated body and exaggerated facial features typical of fin-de-siècle portrait satire. The wood engraving—a medium favored for its crisp lines and rapid reproduction—reduces Pasteur's form to an enormous head perched on a diminished torso, emphasizing intellectual dominance over physical presence. This technique descends from Daumier's mid-century lithographic campaigns and the German satirical tradition, channeling scientific authority into visual mockery. The work reflects the caricaturist's dual impulse: to honor Pasteur's revolutionary germ theory through physiognomic exaggeration while subtly questioning the cult of scientific genius. Such prints shaped early comic visual language, establishing how caricature could both celebrate and critique public figures through distortion.
