Leviathan. Philip Hoare

that in order to hunt in the depths where only one per cent of sunlight penetrates below two hundred metres, the whale uses a ‘unique video-receptor system…which lets the animal obtain the image of objects in the acoustic flow of reflected energy even in complete darkness’. In other words, the sperm whale can see its prey in sound. And just when you think nothing else about this animal could confound you, another theory proposes that the whale’s sonic bursts, and the movement of its head, may cause plankton in the deep water to emit their bioluminescence. In the utter darkness, the leviathan may light its own way to its lunch.

      Even as you leave the Tube station, you remain an underground passenger, conducted through a tiled tunnel before emerging into the shadow of an extravagant cathedral of science. Clinging to the terracotta façade–itself layered to resemble geological strata–is an industrial bestiary: heraldic griffins and scaly medieval fish and, most frightening of all, grinning, toothy pterodactyls, with their obscene storks’ beaks and glaring gargoyle eyes and their leathery wings wrapped about them.

      In the gothic nave, children mill about a blackened diplodocus nonchalantly waving its whiplash tail. A hundred years ago, they would have been greeted by another monster, for here stood the skeleton of a sperm whale, guarded by what appeared to be a Victorian policeman as if it were a prisoner at Pentonville.

      The route comes back like a lost memory. I walk past ichthyosaurs sailing through long-vanished Triassic seas and moth-eaten fauna of the savannah and the jungle, displays out of a dead zoo. Abruptly, the corridor turns into a space more like an aircraft hangar than a museum. There, hanging like one of the model aeroplanes I used to suspend from my bedroom ceiling, is the blue whale, the largest object in the Natural History Museum.

      Contrary to the usual tricks of childhood recollection, it is actually bigger than I remember. Nearly one hundred feet long from the tip of its nose to its twenty-foot flukes, the whale could easily accommodate a large household within its interior. There is something fairy-tale about it, an invention of the Brothers Grimm: its huge mouth has a faint grin, and its disproportionately small eye stares out from its wrinkled socket, part amused, part pleading. Even Linnæus’s name for it is a little Swedish joke: Balænoptera musculus–Balæna meaning whale, pteron, wing or fin, and musculus, both muscular, and mouse.

      I was fooled by this model then, as visitors are now, for this wood and plaster reconstruction is only an approximation of a blue whale, a much more streamlined animal than this bloated model gives credit. Constructed in the 1930s, before anyone had seen an entire living whale in its element, the creators of this whalish effigy relied on carcases hauled out of the water, where they lay deflated like old inner tubes, incapable of bespeaking their true beauty. Like the dinosaurs of Crystal Palace–where we went on another family pilgrimage, to see concrete iguanodons and plesiosaurs stranded in a suburban park–London’s magnificent whale is an object of error and mystification. As a boy, I assumed that inside the model was the animal’s skeleton, like a cathedral tomb containing the bones of a saint. In fact, the whale is hollow, and was made using plaster and chicken wire over a wooden frame constructed on site–as if the great hall had been built around it.

      The idea of a new Whale Hall for the museum had been posited as far back as 1914, but war put a stop to it. The project was revived in 1923, when the museum’s pioneering director, Sidney Harmer, called the Trustees’ attention to ‘the inadequacy of the exhibited series of the larger whales. The subject of whaling is very much in the air at the present time,’ he noted, and he reminded the Trustees that they had ‘frequently expressed their sympathy with efforts to protect whales from extinction’.

      Warming to his theme–on three sheets of pale blue foolscap paper–Harmer declared that ‘under such circumstances it would be natural to expect that such species as the Greenland Whale, the Blue Whale and the Humpback Whale would be illustrated in the Whale Room…to give the visitor a satisfactory idea of what these three important species are like’. It was even suggested that government grants for the relief of unemployment and men disabled by the war might be used. However, the primary reason for the new hall was to promote the work being done by the Discovery expeditions in South Georgia, where scientists were conducting their investigations alongside the British whaling fleet in the Southern Ocean.

      It took almost a decade for Harmer’s spectacular vision to be realized. In June 1929 the new hall was announced–complete with a glass roof framed with steel girders, in the Modernist style–but was not completed until 1931. To fill this grand new space, a life-size whale was proposed, and so in 1933 the museum decided to commission a Norwegian engineer to procure a blue whale, hang it by its tail in an engraving dock, and take a mould of it. The expense of this ambitious scheme was to be allayed by selling the blubber and by marketing models made from the mould to American museums; however, its decidedly ‘experimental nature’ meant that it too was abandoned.

      Five years later, in April 1937, the museum’s Technical Assistant and taxidermist, Percy Stammwitz, suggested that he should make the model in the hall itself. Stammwitz and his son, Stuart, spent nearly two years creating the blue whale, to measurements taken by the scientists in South Georgia. Giant paper patterns, like a dressmaker’s kit, were used to cut out transverse sections in wood, which were then connected at three-foot intervals with slats. Over this armature wire netting was laid to take the final plaster coat; Stuart himself would paint the whale’s eye. It was a long and laborious task, and during its construction the workers used its interior as their canteen–much as Benjamin Waterhouse Hawkins had given a New Year’s Eve dinner in his half-built iguanodon in 1853, a party of scientists that one periodical portrayed as modern Jonahs swallowed by the monster.

      As it rose from its timber foundations, the model resembled a huge ship whose keel had been laid down in the museum’s hall, an ark ready for the launch to save the museum’s species before the flood; or perhaps an inter-war airship, about to be inflated with helium for a transatlantic crossing. Indeed, when it was suspended from the ceiling, painters working on the whale complained that it swayed so much that it made them seasick.

      The finished article looked so realistic that The Times thought it would ‘no doubt be mistaken for a “stuffed” whale by the casual visitor’. On its completion in December 1938, just before the outbreak of war, a telephone directory and coins of the realm were placed inside the model as a kind of time capsule. Thus, on the eve of host-ilities, the placid whale became a memorial to a brief peace, a cetacean cenotaph. It was a giant good luck charm, too, for the warders who put pennies on its flukes to encourage visitors to do the same, much as they might throw coins in a fountain for luck. When the museum closed for the evening, the warders scooped up the takings and spent them in the pub.

      Now there is a notice on one side, and, next to it, a twenty-pence and a ten-pence piece lie on the plaster flukes.

      Please do not throw coins on the whale’s tail. It causes damage. Thank you.

      Other models were made to supplement the display, Stammwitz’s initial attempts to stuff dolphins having proved as unsuccessful as earlier attempts to mould a blue whale. They have been replaced in turn by a flotilla of fibreglass cetaceans, from a tiny Ganges River dolphin to a primeval-looking Sowerby’s beaked whale, all following their leader as if one night she might break open the wall of the gallery and guide her charges down to the Thames and out to sea. Until then, there they hang, biding their time, watching the school parties with their beady glass eyes.

      Below the Whale Hall, in the belly of the building, Richard Sabin, the curator of sea mammals, takes me through automatic doors that lock like a spaceship behind us, sealing the climate-controlled area from the world outside. I follow him, past ranks of giant grey lockers reaching from floor to ceiling. As he opens door after door, their contents are revealed: sections of cetaceans preserved in alcohol and labelled with their Latin binomials, Phocœna phocœna, Tursiops truncatus, Balænoptera physalus. One container, the size of a small fish tank, holds a humpback fœtus; with its mouth agape and its pallid skin, it looks more like a rubber toy.

      The end of the corridor opens into a wide room lined with shelves on which stand jars of pale brown liquid, a sharp contrast to the flickering white hum of the lights overhead. Crammed into each glass column is an animal, ghoulishly
