Dippy

Industrialist Andrew Carnegie financed the acquisition of the skeleton in 1898, as well as the donation of the casts at the beginning of the 20th century.[19][20] His great-grandson, William Thomson, was quoted in 2019 explaining the donations: "By gifting copies to the heads of state of seven other countries as well as the UK, Carnegie hoped to demonstrate through mutual interest in scientific discoveries that nations have more in common than what separates them. He used his gifts in an attempt to open inter state dialogue on preserving world peace – a form of Dinosaur diplomacy."[21]

The London cast of Dippy came about when King Edward VII, then a keen trustee of the British Museum, saw a sketch of the bones at Carnegie's Scottish home, Skibo Castle, in 1902, and Carnegie agreed to donate a cast to the Natural History Museum as a gift. Carnegie paid £2,000 for the casting in plaster of paris, copying the original fossil bones held by the Carnegie Museum (not mounted until 1907, as a new museum building was still being constructed to house it).[22] The 292 cast pieces of the skeleton were sent to London in 36 crates, and the 25.6 metres (84 ft) long exhibit was unveiled on May 12, 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. 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).[23][24]

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.[25]

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.[25] 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.[26]

The cast became an iconic representation of the museum. After 112 years on display at the museum, the dinosaur replica was removed in early 2017 to be replaced by the 25 m (82 ft) long skeleton of a young blue whale, dubbed "Hope". The work involved in removing Dippy and replacing it with the whale skeleton was documented in a BBC Television special, Horizon: Dippy and the Whale, narrated by David Attenborough, which was first broadcast on BBC Two on July 13, 2017, the day before the whale skeleton was unveiled for public display.[27]

Dippy started a tour of British museums in February 2018, mounted on a new, more mobile armature.[28][29] Dippy is and has been on display at locations around the United Kingdom: Dorset County Museum (February 10 – May 7, 2018),[30] Birmingham Museum and Art Gallery (26 May – September 9, 2018),[31] Ulster Museum (September 17, 2018 – January 6, 2019),[32] Kelvingrove Art Gallery and Museum, the Great North Museum, the National Museum of Wales, Number One Riverside in Rochdale, and Norwich Cathedral.[33]

As director of the Carnegie Museums, William Holland supervised the donations of the casts. His trip to Argentina in 1912 was recorded by Holland in his 1913 travel book To the River Plate and Back. Holland noted a poem which had become popular among college students:[23][34]

The statue

In 1999 a public sculpture of Dippy was unveiled on the grounds of the Carnegie Institute and Library complex in the Oakland neighborhood of Pittsburgh, Pennsylvania, in tribute to the 100th anniversary of the discovery of Dippy. The dark, grayish brown life-size fiberglass model weighs 3,300 pounds (1,500 kg), stands 22 feet (6.7 m), and measures 84 feet (26 m) in length. The sculpture was created during a nine-month process from the original fossil. Sited along Forbes Avenue near Schenley Plaza and the lawn of the University of Pittsburgh's Cathedral of Learning, Dippy stands adjacent to the entrances of the Carnegie Music Hall and the Carnegie Museum of Natural History.[37][38]

In addition to its service as a mascot for the museum, Dippy has been seen sporting the Terrible Towel of the Pittsburgh Steelers and the colors of University of Pittsburgh's athletic teams. Sometimes when it's cold out the staff dresses him up with a gigantic scarf.[39] Dippy is a featured Pittsburgh landmark on Yinztagram.[40]
