Hall of Inventors & Engineers

Modelled on The Crystal Palace (Great Exhibition of 1851), London, United Kingdom.

Who stands here

Alan Turing sits just inside the East Entrance, facing the door, so that he is met first: the hall's one statue, Glyn Hughes's bronze of him on a bench with an apple in his hand, on a low cast-iron plinth with a cast plaque at his feet, as the memorial in Manchester has one before him. Then down the nave in order of birth, left and right in turn, from Archimedes to Ada Lovelace; Edison and Tesla face each other across the Crystal Fountain in the transept ('war of the currents'); beyond it the Wright brothers, and Tim Berners-Lee closes the nave at its west end, facing the door. The others each stand on a cast-iron stele made of the building's own parts: two of Paxton's columns either side of the inscribed panel, a lattice girder over it and the transept's fan in small on top, painted in Owen Jones's colours, the words cast and gilt.

The building

The Crystal Palace (Great Exhibition of 1851)

Joseph Paxton's building for the Great Exhibition in Hyde Park, prefabricated in cast iron, timber and sheet glass on a module of 24 ft (7.32 m), the length of its cast-iron girders and three of its 8 ft ridge-and-furrow roofs: 1,848 ft (563 m) long and 408 ft (124 m) wide, in three tiers 24, 44 and 64 ft high stepping in from 408 to 264 and 120 ft; the nave 72 ft wide between galleries 24 ft wide at 22 ft 11 in; hollow cast-iron columns, all 8 in across, that drained the roof; the transept, 72 ft wide under a glazed semicircular vault on timber ribs, 108 ft high, built over a row of elms, its south end the main entrance under a fan of sashes and an electric clock. Paxton's gutters ran the roof's length under canvas; Owen Jones painted the ironwork blue, red and yellow; F. & C. Osler's Crystal Fountain, 27 ft of glass, stood at the crossing.

The model

The walk shows a section at real size and at the true module, laid out from Charles Downes's measured plates and Charles Cowper's description (1852): the whole transept, 408 ft from its south end to its north end, and the nave 156 ft (47.5 m) either side of it, its ends closed by the building's end elevation, so 124 × 95 m. The columns stand on the 24 ft grid with their octagonal bases and the connecting pieces the girders are keyed into; the lattice girders tie them at 22 ft 2 in, 42 ft 2 in and 62 ft 2 in. Within 132 ft of the transept the second tier runs the full width, as the plans show; beyond, the three tiers step in, so the ends show the stepped east front. The fronts are in 8 ft compartments: the ground tier boarded over a plinth of louvres (glazed, with doors, at the entrances), the upper tiers glazed, a light arch in each, the band of louvres behind cast rings at each tier's top, the cornice, its cresting and a flagstaff over every column, flags of the nations on every other. The flat roofs are Paxton's ridge and furrow under the calico that covered them; the transept's vault is clear glass on its ribs, purlins and tie-rods, with lead flats either side; its ends' fan of sashes, the south one with the clock's hours. Owen Jones's colours: the columns' round faces yellow and flat faces blue, the girders blue with red undersides, white between. The floor is deal boards laid with open joints; the light falls as in a glazed and canvassed hall, darker under the galleries, and the far end fades into its haze, as the photographs of 1851 show it; the glass is the green of sheet glass. Four staircases lead to the galleries, which the walker can walk. The north front's 48 ft refreshment wing, the open courts, the exhibits (but for flags hung from the galleries over the nave), the louvres' machinery and the canvas's sag between the ridges are left out; the fan, the clock, the cresting and the flags are drawn from the engravings and the fountain from Ferrier's photograph of 1851, not measured.
