developed from Duchenne's understanding of neural pathways and his diagnostic innovations including deep tissue biopsy, nerve conduction tests (
NCS), and clinical photography. This extraordinary range of activities (mostly in the
Salpêtrière) was achieved against the background of a troubled personal life and a generally indifferent medical and scientific establishment.
Neurology did not exist in France before Duchenne and although many medical historians regard
Jean-Martin Charcot as the father of the discipline, Charcot owed much to Duchenne, often acknowledging him as "''mon maître en neurologie''" (my master in neurology).
The American neurologist
Dr. Joseph Collins (1866–1950) wrote that Duchenne found neurology, "a sprawling infant of unknown parentage which he succored to a lusty youth."
His greatest contributions were made in the myopathies that came to immortalize his name,

This resulted in a lengthy period of personal difficulties for Duchenne with his family and in a prolonged estrangement from his son (who later followed Duchenne into medical practice) and they were only reunited towards the end of his life.
In 1835, Duchenne began experimenting with therapeutic "électropuncture" (a technique recently invented by

After a brief second marriage, Duchenne returned to Paris in 1842 in order to continue his medical research. Here, he did not achieve a senior hospital appointment, but supported himself with a small private medical practice, while daily visiting a number of teaching hospitals, including the
Salpêtrière psychiatric centre. He developed a non-invasive technique of muscle stimulation that used
faradic shock on the surface of the skin, which he called "''électrisation localisée''" and he published these experiments in his work, ''On Localized Electrization and its Application to Pathology and Therapy'', first published in 1855.
A pictorial supplement to the second edition, ''Album of Pathological Photographs'' (''Album de Photographies Pathologiques'') was published in 1862. A few months later, the first edition of his now much-discussed work, ''The Mechanism of Human Physiognomy'', was published.

''The Mechanism of Human Facial Expression''

of man. He is known, in particular, for the way he triggered muscular contractions with electrical probes, recording the resulting distorted and often grotesque expressions with the recently invented camera. He published his findings in 1862, together with extraordinary photographs of the induced expressions, in the book ''Mecanisme de la physionomie Humaine'' (''The Mechanism of Human Facial Expression'', also known as ''The Mechanism of Human Physiognomy'').
Duchenne believed that the human face was a kind of map, the features of which could be codified into universal
taxonomies of
mental states; he was convinced that the expressions of the human face were a gateway to the soul of man. Unlike
Lavater
Johann Kaspar (or Caspar) Lavater (; 15 November 1741 – 2 January 1801) was a Swiss poet, writer, philosopher, physiognomist and theologian.

and other physiognomists of the era, Duchenne was skeptical of the face's ability to express moral character; rather he was convinced that it was through a reading of the expressions alone (known as

''The Mechanism of Human Physiognomy''in 1862 (also entitled, ''The Electro-Physiological Analysis of the Expression of the Passions, Applicable to the Practice of the Plastic Arts''. in French: ''Mécanisme de la physionomie humaine, ou Analyse électro-physiologique de l'expression des passions applicable à la pratique des arts plastiques''), now generally rendered as ''The Mechanism of Human Facial Expression''. The work compromises a volume of text divided into three parts:
# General Considerations,
# A Scientific Section, and
# An Aesthetic Section.
These sections were accompanied by an atlas of photographic plates. Believing that he was investigating a God-given

of facial signs, Duchenne writes:
In the face our creator was not concerned with mechanical necessity.
He was able in his wisdom or – please pardon this manner of speaking – in pursuing a divine fantasy … to put any particular muscles into action, one alone or several muscles together, when He wished the characteristic signs of the emotions, even the most fleeting, to be written briefly on man's face. Once this language of facial expression was created, it sufficed for Him to give all human beings the instinctive faculty of always expressing their sentiments by contracting the same muscles.
This rendered the language universal and immutable.
Duchenne defines the fundamental expressive gestures of the human face and associates each with a specific facial muscle or muscle group. He identifies thirteen primary

s the expression of which is controlled by one or two muscles. He also isolates the precise contractions that result in each expression and separates them into two categories: partial and combined. To stimulate the facial muscles and capture these "idealized" expressions of his patients, Duchenne applied faradic shock through electrified metal probes pressed upon the surface of the various muscles of the face.
Duchenne was convinced that the "truth" of his pathognomic experiments could only be effectively rendered by photography, the subject's expressions being too fleeting to be drawn or painted. "Only photography," he writes, "as truthful as a mirror, could attain such desirable perfection." He worked with a talented, young photographer,
Adrien Tournachon, (the brother of
Felix Nadar), and also taught himself the art in order to document his experiments. From an art-historical point of view, the ''Mechanism of Human Physiognomy'' was the first publication on the expression of human emotions to be illustrated with actual photographs. Photography had only recently been invented, and there was a widespread belief that this was a medium that could capture the "truth" of any situation in a way that other mediums were unable to do.
Duchenne used six living models in the scientific section, all but one of whom were his patients. His primary model, however, was an "old toothless man, with a thin face, whose features, without being absolutely ugly, approached ordinary triviality." Through his experiments, Duchenne sought to capture the very "conditions that aesthetically constitute beauty." He reiterated this in the aesthetic section of the book where he spoke of his desire to portray the "conditions of beauty: beauty of form associated with the exactness of the facial expression, pose and gesture."
[Duchenne, ''Mecanisme'', part 3, 133; Cuthbertson trans., 102] Duchenne referred to these facial expressions as the "gymnastics of the soul". He replied to criticisms of his use of the old man by arguing that "every face could become spiritually beautiful through the accurate rendering of his or her emotions",

condition of the face, he could experiment upon the muscles of his face without causing him pain.
Aesthetics and The Narrative Setting
![Duchenne-FacialExpressions](https://upload.wikimedia.org/wikipedia/commons/0/08/Duchenne-FacialExpressions.jpg)
Whereas the scientific section was intended to exhibit the expressive lines of the face and the "truth of the expression," the aesthetic section was intended also to demonstrate that the "gesture and the pose together contribute to the expression; the trunk and the limbs must be photographed with as much care as the face so as to form an harmonious whole." For these plates Duchenne used a partially blind young woman who he claimed "had become accustomed to the unpleasant sensation of this treatment …". As in many of the plates for the scientific section, this model was also stimulated faradically to provoke a different expression on either side of her face. Duchenne advised that looking at both sides of the face simultaneously would reveal only a "mere grimace" and he urged the reader to examine each side separately and with care.
Duchenne's experiments for the aesthetic section of the ''Mechanism'' included the use of performance and narratives which may well have been influenced by gestures and poses found in the

, of cruel instincts," modulated to varying degrees of contrary feelings of filial piety. This theatre of pathognomic effect dominates the aesthetic section of the ''Mecanisme''.
Beauty and Truth
To help him locate and identify the facial muscles, Duchenne drew heavily upon the work of
Charles Bell, who had included psychiatric patients in his studies. Duchenne may have avoided photographing the "passions" of the insane because of technical problems at the time; however, it is more likely that he did so for aesthetic reasons – that he did not regard the expressions of the insane as socially acceptable. Charles Bell's writings also showed an instinctive revulsion for the mentally ill.
The exact imitation of nature was for Duchenne the

sculptors for unquestionably attaining an ideal of beauty, he nevertheless criticized them for their
anatomical errors and failure to attend to the emotions. Thus at the end of the scientific section, for instance, Duchenne "corrects" the expressions of three widely revered classic Greek or Roman antiquities: In no manner, argues Duchenne, do any of these countenances conform to nature as revealed by his electrophysiological research. He even questions the Greek artist
Praxiteles's accuracy in sculpting the

In Greek mythology, Niobe (; grc-gre, Νιόβη ) was a daughter of Tantalus and of either Dione, the most frequently cited, or of Eurythemista or Euryanassa, the wife of Amphion and the sister of Pelops and Broteas.

Would Niobe have been less beautiful if the dreadful emotion of her spirit had bulged the head of her oblique eyebrow as nature does, and if a few lines of sorrow had furrowed the median section of her forehead? On the contrary, nothing is more moving and appealing than such an expression of pain on a young forehead, which is usually so serene.

He even named an examination room at the asylum after his teacher. Like Duchenne, Charcot sought to chart the gestures and expressions of his patients, believing them to be subject to absolute, mechanistic laws. However, unlike Duchenne, who restricted his experiments to the realm of the sane, Charcot was interested almost exclusively in photographing the expressions of traumatized patients - the "hysterics". He is also known for enabling the public to witness these emotional displays by establishing his renowned weekly "theatre of the passions" for the fashionable society of the day to witness the expressions of the insane.

Perhaps we can best understand Duchenne's contribution to art and science by Robert Sobieszek's concluding words to his comprehensive chapter on Duchenne, in his book ''Ghost in the Shell'' where he writes:
Duchenne's ultimate legacy may be that he set the stage, as it were, for Charcot's visual theater of the passions and defined the essential dramaturgy of all the visual theaters, both scientific and artistic, that have since been conceived in the attempt to picture our psyches. … In the end, Duchenne's ''Mecanisme de la Physionomie Humaine'' and the photographic stills from its experimental theater of electroshock excitations established the modern field on which the struggle to depict and thus discern the ever-elusive meanings of our coded faces continues even now to be waged.[Sobieszek, ''Ghost in the Shell'', 2003, MIT Press, 79]
