Authorized edition
In this book, Darwin seeks to trace the animal origins of human characteristics, such as the pursing of the lips in concentration and the tightening of the muscles around the eyes in anger and efforts of memory. It was published thirteen years after On The Origin of Species and is, alongside his 1871 book The Descent of Man, Darwin's main consideration of human origins. . Darwin sought out the opinions of some eminent British psychiatrists, notably James Crichton-Browne, in the preparation of the book, which forms Darwin's main contribution to psychology.
The Expression of the Emotions is also an important landmark in the history of book illustration. The published book assembled illustrations rather like a Victorian family album, with engravings of the Darwin family's domestic pets by the zoological illustrator T. W. Wood, Mr. Riviere and Mr. A. May, portraits by the Swedish photographer Oscar Rejlander (1813–1875), anatomical diagrams by Sir Charles Bell (1774–1842) and Friedrich Henle (1809–1885), and illustrational quotations from the Mécanisme de la Physionomie Humaine – Analyse Electro Physiologique de L'Expression des Passions (1862) by the French neurologist Guillaume-Benjamin Amand Duchenne de Boulogne (1806–1875).

Charles Robert Darwin (1809 – 1882) was an English naturalist and geologist, best known for his contributions to evolutionary theory. He established that all species of life have descended over time from common ancestors, and in a joint publication with Alfred Russel Wallace introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.
