Jumeau's second son Emile-Louis, born in 1843, who built the "Château Jumeau" or "Villa Jumeau" in Longny-au-Perche in 1866, began assuming management of the company and in 1877 he introduced the "Bébé Incassable", with a head made by Jumeau, the face of a young girl and a fully articulated composition body. Jumeau's dolls were fashionably dressed in the styles popular at the time, and often had shapely mature figures. As with modern Barbie dolls, large ranges of clothing styles and accessories were made available. In 1878 the company was awarded a gold medal at the Paris Exhibition, an honour which was proudly advertised on all their products. Further awards followed at the International Exhibitions in Sydney in 1879 and Melbourne in 1880. In 1885, at the Antwerp Exhibition, Jumeau's dolls won the "Diplôme d’Honneur", an award subsequently commemorated by being stamped on every doll made. The golden age of the company spanned the period from the late 1870s to the late 1890s when the company employed over 200 workers with an annual output of 100 000 dolls.
