World exhibitions became a new phenomenon in the West in the nineteenth century. Scientific and technical progress were shown. About a dozen World Fairs were organised during the second half of the nineteenth century. Seven times an international invitation chess tournament was part of the event (London 1851, London 1862, Paris 1867, Vienna 1873, Philadelphia 1876, Paris 1878, Paris 1900). The third tournament took place in the Grand Cercle, 10 boulevard Montmartre, Paris, from 4 June to 11 July. Thirteen participants played in a double round-robin tournament. Draws counted as zero. The time control was ten moves an hour.
