Yet Darwin's caution was arguably rewarded: the
intervening years, from initial discovery to publication, had not only
witnessed the public become increasingly receptive towards new ideas
but the growth of Darwin's reputation and respectability. A theory
that would have been dismissed out of hand by established academics
years before, was now given serious, if guarded, consideration.
The Expression played a significant role in bringing photographic evidence into the scientific world: the photographs in the book constitute one of the earliest examples of attempting to freeze motion for analysis.10 Photography was still a relatively new art form at the time of the Expression's publication. Nevertheless, Darwin believed that it would hold an advantage over other forms of representation since its potential for capturing fleeting expressions with accuracy and detachment would prove more objective. His publisher, John Murray, was less enthusiastic. He warned that it would be necessary to glue photographs into every copy, making their inclusion very labour intensive and costly. The photographer Ernest Edwards (1837-1903) was to provide the solution. Edwards had invented a new photomechanical method of reproducing photographs called heliotype.

Heliotype permitted mass production since it used printing plates
rather than relying on individual prints. It involved coating each
plate with light-sensitive gelatine emulsion, which was then exposed
photographically using an ordinary negative. The emulsion developed
tiny fissures corresponding to the negative - a relief copy - which
was then inked, run through the presses and printed on ordinary paper.11
However Darwin's problems were not at an end: gathering appropriate photographs of human expressions was to prove tricky. He required images of fleeting actions occurring over a fraction of a second, the sort of instantaneous images that contemporary photographers found difficult to produce. Early photographic materials were extremely awkward, unpleasant and time consuming to use and normal exposure times, depending on conditions, ranged from several seconds to two minutes. Not ideal for capturing ephemeral expressions.12 Darwin searched high and low for appropriate images and the ones eventually included were to come from five different photographers. The first suitable images Darwin located already existed in a scientific treatise published a decade earlier by the physiologist Guillame-Benjamin Duchenne (1806-1875). Duchenne, a French doctor, believed that certain neurological problems and muscle disorders were linked to electrical dysfunction within the human body. |

He devised a way of inducing neural action by applying electrical
currents to patients' heads. He learned that it was possible -
particularly with one specific patient - to use the technique to
artificially generate different expressions that could be fixed long
enough for photographs to be taken. With Duchenne's permission, Darwin
used eight of these images in his Expression. Darwin also used images of young children (notoriously difficult to capture due to their inability to stay still) taken by photographers Adolph Kindermann (1823-1892) and George Charles Wallich (1815-1899). Additionally he received numerous photographs of mentally-ill patients from James Crichton-Browne (1840-1938), physician and director of the West Riding Lunatic Asylum. However, only a single engraving from one of Crichton-Browne's images was included in Expression. The numerous woodcuts included in the Expression were cheaper alternatives to the photographs that Darwin would undoubtedly have preferred but could not afford. Interestingly, in some cases, the engravings are not faithful reproductions of the original images. In the engravings from Duchenne's photographs, the electrical apparatus have been removed entirely. |

The photographer to have the most influence on the
Expression was
Oscar Rejlander (1813-1875), who contributed nineteen of the thirty photographs. Rejlander was a photographic pioneer who strongly believed that
photography had a role in fine art. Having trained first
as a painter, he later turned his hand to the camera, believing
the process could create images every bit as beautiful and meaningful
as any other medium. By the time Darwin and he met,
Swedish born Rejlander had already achieved a degree of fame for his
composite photographs, in which he created elaborate compositions by
combining details from several negatives in a single print.14
In addition to providing one of his famous images of a crying child for inclusion in the Expression, Rejlander and his wife posed for many of the photographs in the work. They can be seen pulling various exaggerated and histrionic gestures, in the belief that such manipulation was necessary to produce convincing illustrations.15 |

With hindsight, it is easy to conclude that the manipulation
evident in both Rejlander's photographs and the engravings taken from Duchenne's
images undermine Darwin's claims to objectivity and
authenticity. While criticisms are justified by modern standards,
photographic historian Phillip Prodger notes that, in the
Expression,
"the distinction between evidence and illustration is blurred because
there is little precedent for the acceptance of photographs as
scientific data. Rules about photographic objectivity did not yet
exist, in part because photographers frequently found it necessary to
manipulate their work to enhance the visual appeal and clarity of
their images."16 The Expression marked the birth of the use of photographs as scientific evidence; obviously, it could not conform to the rules of objectivity and authenticity expected today since such rules were only agreed in debates which acknowledged the Expression's compromises and flaws. Despite the worldwide fame of Darwin and his Origin, relatively few - even in scientific fields - will be overly familiar with his Expression. Concern over the authenticity of the photographs is one possible explanation for why the Expression may have become overlooked for so long. However, a number of other reasons can also be considered. |

One factor contributing to its decline was its tendency towards
"Lamarckian" ideas. Many years before Darwin, the 18th century French
biologist, Jean-Baptiste Lamarck (1744-1829), proposed an alternative - and widely
discredited - theory of evolution. He suggested that through practice
and repetition animals can improve their bodies during life,
adaptations that will be passed on to their children. This theory,
sometimes described as use-inheritance, was quite different from
Darwin's notion of randomly occurring beneficial traits being
preserved through improved chances of survival and breeding success. Initially, Lamarck's
theory was completely disregarded by Darwin; however later, when
revisiting his ideas and modifying his theories to answer critics, he
began to believe that such use-inheritance had a place in the
evolutionary process.17 In the Expression, Darwin describes a form of "Lamarckian" use-inheritance called the principle of serviceable associated habits. It posits that a deliberate action taken when experiencing a specific emotion, if repeated, might become associated through habit, and later be called up by that emotion alone. Such connections, Darwin proposed, might be inherited by succeeding generations. The scientific disproof of use-inheritance appeared just seven years after Darwin's death, and undoubtedly damaged the Expression's scientific standing.18 |
Another blow to the work was its perceived anthropomorphism. In
the early years of the 20th century, the dominant movement in biology
was towards behaviourism. This approach stated that it was
unscientific to describe what animals did in terms of emotion:
scientists should describe only observable behaviour rather than
attempting to make any inferences about motivation. The Expression therefore, was
soon thought to describe an outmoded and flawed approach.19
Paul Ekman, a psychologist who has written extensively on the Expression, believes that perhaps the most important reason for its fall from favour is the same reason why it has become increasingly relevant once again. The "democratic zeitgeist" of the 20th century, with its "hope that all men could be equal if their environments were equally benevolent", did not sit comfortably with Darwin's biological determinism. The cultural relativism that dominated 20th century social science considered environment as the sole important factor in controlling behaviour. With its claims that expressions are innate, determined by our evolutionary past, Darwin's work did not conform in a world that "reject[ed] inheritance for metaphysical reasons".20 Today most scientists believe that both nature and nurture play a role in all human behaviour. Consequently, the Expression, with its many insights into early human development, has once again been embraced by the scientific community. |

As mentioned above, this year marks the bicentenary of
Charles Darwin's
birth. However it also marks 150 years since, On the
Origin of Species, was first published. Described as, "the most famous book in
science", the Origin has received overwhelming media attention
over the years, particularly during this current celebration.
The University of Glasgow Library is fortunate to boast two copies of
the first edition of Origin; however, in
light of the considerable column inches already devoted to the work
elsewhere, and acknowledging geneticist Steve Jones' comment that, "to
remember [the Origin] alone would be as
foolish as to celebrate Shakespeare just as the author of
Hamlet",21 we chose the path less
travelled by concentrating on the
Expression for this month's discussion.
We are fortunate to hold three copies of the Expression: the featured copy comes from our Dougan Collection. Containing a wealth of early photographic material, the collection was purchased in 1953 from Robert O. Dougan, then Deputy Librarian of Trinity College, Dublin, and subsequently Librarian of the Huntington Library, California. |
