In describing new discoveries, or when writing for a wider audience, natural historians in the past accompanied their observations with illustrations, some of which were made by others and some of which they made themselves. At the forefront of natural historian/illustrators is Philip Henry Gosse, whose father, a professional artist, taught his son to paint in watercolour, a medium that he used to great effect. He also made a large number of line drawings.
Nowadays, there are many means of producing beautiful and informative illustrations using photography and digital methods and we see the beginning of the transition to these media in Alister Hardy’s “The Open Sea: The World of Plankton”. The book is illustrated by black-and-white photographs taken by Douglas P. Wilson and line drawings and paintings made by Hardy himself. Wilson encountered problems when taking photographs of deep-sea animals that had been brought to the surface as the accurate portrayal of their colours required long exposures that were not practical in the 1950s. This is what Hardy wrote [1]:
It was my hope, and that of the editors, that in addition to his black-and-whites Dr Wilson would have been able to contribute a series of colour photographs of the living plankton and especially of the richly pigmented animals from the ocean depths. At that time the electronic flash was only just being developed and he felt unable to attempt them.
It’s a reminder of how much we take beautiful images, films, videos, etc. for granted in the modern era. In the Introduction to “The Open Sea: The World of Plankton” Hardy describes his technique for making illustrations and this is worth quoting in full [1]:
All save seven of the 142 drawings in the plates were made from living examples or, in a few cases, from those taken freshly from the net when some deep-water fish and plankton animals were dead on reaching the surface.. .. It may be of interest to record how the drawings were made. All the animals, except the larger squids and jelly-fish, were drawn either swimming in flat-glass dishes placed on a background of millimetre squared paper where they were viewed with a simple dissecting lens, or on a slide under a compound microscope provided with a squared micrometer eyepiece; in either case the drawings were first made in outline on paper which had been ruled with faint pencil lines into squares which corresponded to those against which the specimen was viewed. In this way the shape and relative proportions of the parts could be drawn in pencil and checked and rechecked with the animal until it was quite certain they were correct. The outline was then gone over with the finest brush to replace the pencil by a permanent and more expressive water-colour line; were rubbed out and the full colouring of the drawing proceeded with.
Here are some examples (more are given at the end):
It is tempting to suggest that their style, especially the dark-field paintings, were influenced by the illustrations in Gosse’s “A Naturalist’s Rambles on the Devonshire Coast” [2]. Certainly, both natural historians appreciated that a lively text is boosted by quality images, but few have the talent, and patience, of Gosse and Hardy.
“The Open Sea: The World of Plankton” was completed at a time when natural history was beginning to be overtaken by deterministic approaches for the study of living organisms. After the structure of DNA was elucidated by Crick and Watson [and others], many began to see the possibility of understanding living creatures by looking at their biochemistry linked to their genetics. This bottom-up approach now dominates academic Biology, and even ecologists, who look at very complex systems with many variables, are fond of reductionist modelling in an attempt to understand what they observe and measure.
Alister Hardy (above) was appointed Linacre Professor of Zoology at Oxford University in 1945, one of the most prestigious appointments offered by any university. In the biography written to celebrate his life, published by the Royal Society [3], we read:
In his inaugural address he looked forward to the encouragement of field studies in ecology and behaviour. In his teaching the direction was away from comparative anatomy and towards general zoology. His colleague, Dr Peter Brunet, saw him as foremost a naturalist who encouraged observation rather than analysis. Physicochemical explanations of life, which left no room for awe, did not attract him. There was still a nature mystic within him.
It is an approach that is valuable, and natural history should be taught more extensively in our current age: a contrast to the mechanistic view that promotes the idea that answers will eventually be found for nearly everything about living creatures, communities and ecosystems.
Gosse promoted the idea of a sense of wonder in many of his books, especially in “The Romance of Natural History” that was published in two series in 1860 and 1861 [4,5]. Gosse was driven by a profound belief in the literal truth of the Bible and saw everything in terms of God’s Creation. Hardy’s mysticism was less rigid and more wide-ranging and he went on to establish a foundation dedicated to “a future science of natural theology” [6], the papers of which are now held at the University of Wales Trinity Saint David at Lampeter [7]. Whether one uses theistic, or atheistic, explanations, a sense of awe at what one sees in the natural world is invaluable for interpreting our sense of being.
Hardy and Gosse are fascinating natural historians from whom we can learn much.
(Of course, I had no possibility of meeting Gosse in person and I never met Alister Hardy, who died as recently as 1985. However, I claim one small claim to contact with the latter, as one of my University Tutors was Michael Hardy, Sir Alister Hardy’s son).
