Emile Baudement (1810 - 1864), invented a radical new view of animal husbandry at the Institute of Agriculture at Versailles, France in 1848. Baudement introduced the idea that the deliberate delivery of nutrition, selective reproduction, and increased physical care for livestock could influence the quantity and quality of their production for food and thereby increase profits for farms. In 1856, he published a folio with illustrations of a variety of breeds of domestic bovines, Les Races Bovines au Concours Universel Agricole, from which these prints are taken. The plates were produced by a mixed process of photographic transposing on to a metal plate (heliography) followed by handwork of various kinds - soft ground etching, mezzotint and aquatint, the background tint being achieved by lithography. The coloring, which is beautifully and subtly done, is modern. Size (in): 13.75 x 18
