A photograph of various philosophical instruments, including balances, a coin-weighing machine and an air-pump, manufactured by Deleuil, shown at the Great Exhibition, taken by Claude-Marie Ferrier in 1851.
The Great Exhibition of the Works of Industry of All Nations, held in 1851 in the purpose-built Crystal Palace, Hyde Park, London, was the first industrial exhibition. Over 100,000 exhibits were shown from around the world.
This photograph is an illustration from 'Reports by the Juries' (1852), a four-volume work on the contents of the exhibition, illustrated with 155 photographs by Claude-Marie Ferrier and Hugh Owen (1804-1881). Only 140 presentation sets of this work were produced, to be given to notables of those countries which participated in the exhibition as a record of the great event.
