The artistic education of Pierre-Georges Jeanniot began with his father, Pierre-Alexandre Jeanniot (1826–1892), a longtime director of l'École des Beaux-Arts of Dijon, France. Pierre-Georges Jeanniot started out pursuing a military career and quickly rose through the ranks serving in various regiments. He never ceased drawing though and in 1872 he exhibited a small watercolor entitled Intérieur de forêt at the Salon de Paris, The next year he presented the painting Le Vernan à Nass-sous-Sainte-Anne. From then on he became a regular contributor to the Salon de Paris, exhibiting landscapes and figurative works. In 1881, after the army offered him the rank of commandant, he resigned to devote himself exclusively to painting. He took up residence in Paris. His works from this period represent mainly scenes of military life that allowed him to forge a reputation which was cemented over the next few years with the winning of some significant prizes and awards. Tiring of military subjects, he started painting the Parisian women of La Belle Epoque, promenading on the streets of Paris or scenes on the racecourse. These paintings provide us a vivid sociological portrayal of his times. In Paris, he secured himself friendships with Édouard Manet, Pierre Puvis de Chavannes, Jean-Louis Carnival, Paul Helleu, and especially with Edgar Degas, whom he revered as a master. He would spend many weekends with Edgar Degas in his family home in Diénay. He was gifted with many talents and excelled with his drawings. He showed in his drawings his passion and his artistic strength. They are vivacious, expressive and enthusiastic, while at the same time, rendering with a sense of humour the picturesque scenes of daily life. During the next decades he illustrated a large number of literary books. His works can be found in many French museums, including those in Alais, Nancy, Paris, Carnavalet, Pau and Toulouse and overseas in Oslo, New York and Buenos Aires.
