Early history

The 292 cast pieces of the skeleton were sent to London in 36 crates, and the 21.3 metres (70 ft) long exhibit was unveiled on 12 May 1905, to great public and media interest, with speeches from the museum director Professor Ray Lankester, Andrew Carnegie, Lord Avebury on behalf of the trustees, the director of the Carnegie Museum William Jacob Holland, and finally the geologist Sir Archibald Geikie.

Reptile Gallery

The cast was mounted in the museum's Reptile Gallery to the left of the main hall (now the gallery of Human Biology) as it was too large to display in the Fossil Reptile Gallery (to the right of the main hall; now the gallery of Creepy Crawlies).

Carnegie paid to have additional casts made for display in many European capitals – including Berlin, Paris, Vienna, Bologna, St Petersburg and Madrid; one sent to Munich was never erected – as well as Mexico City and La Plata in Argentina, making Dippy the most-viewed dinosaur skeleton in the world. The cast in London quickly became an iconic representation of the museum, and has featured in many cartoons and other media, including the 1975 Disney comedy One of Our Dinosaurs Is Missing.

Dippy was taken to pieces and stored in the museum's basement during the Second World War to protect it from bomb damage, and reinstalled in the Reptile Gallery after the war. The original presentation of the cast was altered several times to reflect changes in scientific opinion on the animal's stance. The head and neck were originally posed in a downwards position, and were later moved to a more horizontal position in the 1960s.

Move to Hintze Hall

Dippy was removed from the Reptile Gallery in 1979 and repositioned as the centrepiece of the main central hall of the museum, later renamed the Hintze Hall in recognition of a large donation by Michael Hintze. Dippy replaced a mounted African elephant, nicknamed George, which had been on display as the central exhibit in the main hall since 1907, with various other animal specimens. The elephant had itself replaced the skeleton of a sperm whale which was the first significant exhibit in the hall and had been on display since at least 1895: earlier, the hall had been left largely empty.

Dippy was originally displayed alongside a cast of a Triceratops skeleton, which was removed around 1993. The tail of the Diplodocus cast was also lifted to waft over the heads of visitors; originally it drooped to trail along the floor.

After 112 years on display at the museum, the dinosaur replica was removed in early 2017 to be replaced by the skeleton of a young blue whale, 25 metres (82 ft) long, dubbed "Hope", suspended from the ceiling. The whale had been stranded on sandbanks at the mouth of Wexford Harbour, Ireland in March 1891. Its skeleton was acquired by the museum and had been displayed in the Large Mammals Hall (originally the New Whale Hall) since 1934.

Dippy returned to the Natural History Museum as part of a temporary exhibition in June 2022, after which the museum intended to relocate the replica to a new location as part of a 3-year loan. In February 2023 it was moved to the Herbert Art Gallery and Museum in Coventry^[2]
