Thus, he spent the years 1878 to 1879 in Brussels, gathering new inspirations and expanding his skills. Towards the end of his life, he began decorative painting of large-scale floral compositions, including an impressive work depicting the flowers of the four seasons in the 7th arrondissement girls' school. His studio was located at No. 32 Rue des Dames in the 17th arrondissement in Paris, a place closely associated with the city's vibrant art scene. Cauchois' contribution to the art world was recognized during his lifetime. He made his debut at the Salon de Paris in 1874 and presented his work several times at the Salon of the Société des Artistes Français, where he became a member in 1890. His work won several awards, including a 3rd class medal in 1898 and a 2nd class medal in 1904. After his death in Paris on October 11, 1911, Cauchois left behind an impressive collection of artworks that reflect his unparalleled talent and deep love of flower painting.
