James Wyld(1812–1887) was a British geographer and map-seller. He was the eldest son of James Wyld the Elder (1790–1836) and Eliza (née Legg). In 1838, he married Anne, the daughter of John Hester, and had two children, one of whom, James John Cooper Wyld also became a map publisher.
On his father's death in 1836, Wyld became the sole owner of the thriving family mapmaking business based in Charing Cross. His maps, which covered regions as diverse as London and the gold fields of California, were regarded highly, and Wyld himself had an excellent reputation as a mapmaker; he was elected as a fellow of the Royal Geographical Society in 1839, and he was appointed Geographer to Queen Victoria and Prince Albert (as had been his father before him).
Wyld was best known for his"Great Globe" an attraction situated in London's Leicester Square between 1851 and 1862 At the centre of a purpose-built hall was a giant globe, 60 feet 4 inches (18.39 m) in diameter. The globe was hollow and contained a staircase and elevated platforms which members of the public could climb in order to view the surface of the earth on its concave interior, modelled in plaster of Paris, complete with mountain ranges and rivers all to scale. Punch described the attraction as "a geographical globule which the mind can take in at one swallow." In the surrounding galleries were displays of Wyld's maps, globes and surveying equipment.
Wyld originally proposed that the globe should be constructed at the Great Exhibition, but its size and Wyld's desire to run it as a promotional venture precluded it from being featured inside the Crystal Palace, so Wyld negotiated with the owners of the gardens of Leicester Square, and after much wrangling secured an agreement to site it there for ten years. The exhibition hall and model of the Earth were hastily constructed to coincide with the Great Exhibition.
