For the following resumé I am indebted to Dr Clow's pioneering examination of the subject in Annals of Science, September 1956.
Although the picture is entitled 'Distinguished Men of Science 1807-8' it is in fact a Victorian concoction conceived in about 1856 and published as an engraving in 1862. Described in a letter from William Walker's son (of the same name) to the NPG:
The Drawing of the "Distinguished Men of Science living in 1808" was the last work my Father was engaged on. Sir John Gilbert designed the grouping & general effect. J. F. Skill then worked on the drawing & my Father finished it, the greatest care was taken in getting the likenesses correct & every available means employed so that the likenesses remained almost standards. My Father then engraved the plate with the assistance of George Zobel. The idea of the work was his own conception & altogether occupied six years in carrying out.
(Letter from William Walker to Lionel Cust 12 November 1896, MS in NPG archive.)
Walker and Gilbert had already combined to produce the engraving of 'The Aberdeen Cabinet Deciding upon the Expedition to the Crimea in 1854', published in 1857, and this new venture was begun at about that time. Dr Clow suggests that a further incentive may have been the publication in 1845-6 of Lord Brougham's essay, Lives of Men of Letters and Science in the Time of George III. Gilbert's original sketches (NPG 1383a) with their revealing titles disclose its evolution from little more than a jotting to the final engraving - six years during which, although the basic design remained static, several changes were made in the choice of figures to be included. The Swedish chemist Berzilius was replaced by Dundonald who in turn gave way to William Smith. Peel was replaced by Ronalds, Beaufort and later Fourdrinier were removed, and four newcomers added: Chapman, Frodsham, Troughton and Watson. The final selection demonstrates the Victorian definition of 'Men of Science' as being in fact 'Men of Technology'. The focal point is James Watt and a group of engineers surrounded by chemists and physicists.
The choice of venue is significant. Although over half the sitters are Fellows of the Royal Society they are assembled in the library of the Royal Institution under the great convex glass, a considerable technical feat at the time, still in position there today. The signatures were carefully copied by Walker from various sources and transferred first to the drawing then to the engraved plate. His letter of 19 November 1858 to the Secretary of the Royal Society asks for permission to trace with a soft lead pencil signatures of 26 Fellows: Allen, Baily, Banks, Berzilius, Brown, Brunel, Cartwright, Cavendish, Dalton, Davy, Gilbert, Hatchett, Henry, Herschel, Huddart, Jenner, Kater, Leslie, Maskelyne, Playfair, Rennie, Ronalds, Rumford, Watt, Wollaston, Young (Royal Society Misc. Corr., 5, p 372). It has been possible to find the origins of most of the portraits. A great deal of trouble was taken by Walker to make use of suitable originals, the only failure being Bramah who had to be shown back view. An advertisement for the project dated 4 June 1862, the date of publication of the engraving, says:
The Portraits are in every possible case taken from Originals of the greatest merit, and Mr Walker thankfully acknowledges the aid extended to him by many private Gentlemen, especially Dr William Sharpey (Secretary of the Royal Society) and Mr Woodcroft (Superintendent of the Patent Office) by whom every facility has been offered for making copies from many unique originals in the Patent Museum and Portrait Gallery formed by him.
Except for the daguerreotype of Donkin and a photograph of Ronalds, probably by Walker himself, they were mostly engravings from paintings, drawings or miniatures, which were then copied or adapted by Frederick Skill and arranged in the groups decided on by Gilbert.
In 1864-5 William Walker and his two sons were considering a companion picture, 'Men of Science Living in 1846-7', many of the portraits to be based on photographs taken in their own studio in Margaret Street: 'there is a real advantage in doing this because I take several views of the countenance in the right light and shade best suited for my purpose of grouping ...'. Letters in the Royal Society library intimate that Sir John Herschel was to be the central figure of this group; an appointment was made at the studio for 26 July 1865 (Herschel Letters, 18, pp 18-20). Walker died in 1867 and the project was never completed.
