               Fire Devastates Brazil's Oldest Science Museum

The overnight inferno likely claimed fossils, cultural artifacts, and more irreplaceable collections amassed over 200 years.

Major pieces of Brazil's scientific and cultural heritage went up in smoke on September 2, as a devastating fire ripped through much of Rio de Janeiro's Museu Nacional, or National Museum. Founded in 1818, the museum is Brazil's oldest scientific institution and one of the largest and most renowned museums in Latin America, amassing a collection of some 20 million scientifically and culturally invaluable artifacts.

The Museu Nacional's holdings include Luzia, an 11,500-year-old skull considered one of South America's oldest human fossils, as well as the bones of uniquely Brazilian creatures such as the long-necked dinosaur Maxakalisaurus. Because of the auction tastes of Brazil's 19th-century emperors, the Museu Nacional also ended up with Latin America's oldest collection of Egyptian mummies and artifacts.

Even the building holds historical importance: It housed the exiled Portuguese royal family from 1808 to 1821, after they fled to Rio de Janeiro in 1807 to escape Napoleon. The complex also served as the palace for Brazil's post-independence emperors until 1889, before the museum collections were transferred there in 1902. In an September 5 email, Museu Nacional curator Débora Pires wrote that the entomology and arachnology collections were completely destroyed, as was most of the mollusk collection. However, technicians had braved the fire to save 80 percent of the mollusk holotypes—the specimens that formally serve as the global references for a given species. The museum's vertebrate specimens, herbarium, and library were housed separately and survived the fire.

An Irreplaceable Loss

It's not yet clear how the fire started, but it did begin after the museum was closed to the public, and no injuries have yet been reported. Firefighters worked through the night to douse the burnt-out shell of the main building, but it seems the blaze has already seared a gaping hole in many scientists' careers.

“The importance of the collections that were lost couldn't be overstated,” says Luiz Rocha, a Brazilian ichthyologist now at the California Academy of Sciences who has visited the Museu Nacional several times to study its collections. “They were unique as it gets: Many of them were irreplaceable, there's no way to put a monetary value on it.”

“In terms of [my] life-long research agenda, I'm pretty much lost,” says Marcus Guidoti, a Brazilian entomologist finishing up his Ph.D. in a program co-run by Brazil's Federal University of Rio Grande do Sul.

Guidoti studies lace bugs, an insect family with more than 2,000 species worldwide. The Museu Nacional held one of the world's largest lace bug collections, but the fire likely destroyed it and the rest of the museum's five million arthropod specimens. “Those type specimens can't be replaced, and they are crucial to understand the species,” he says by text message. “If I was willing to keep working on this family in this region of the globe, this was definitely a big hit.”

Paleontologist Dimila Mothé, a postdoctoral researcher at the Federal University of the State of Rio de Janeiro, adds that the blows to science extend beyond the collections themselves. “It's not only the cultural history, the natural history, but all the theses and research developed there,” she says. “Most of the laboratories there were lost, too, and the research of several professors. I'm not sure you can say the impact of what was lost.”

Brazil’s indigenous knowledge also has suffered. The Museu Nacional housed world-renowned collections of indigenous objects, as well as many audio recordings of indigenous languages from all over Brazil. Some of these recordings, now lost, were of languages that are no longer spoken.

“I have no words to say how horrible this is,” says Brazilian anthropologist Mariana Françozo, an expert on South American indigenous objects at Leiden University. “The indigenous collections are a tremendous loss … we can no longer study them, we can no longer understand what our ancestors did. It’s heartbreaking.” 

On Monday, The Brazilian publication G1 Rio reported that ashes of burned documents—some still flecked in notes or illustrations—have rained down from the sky more than a mile away from the Museu Nacional, thrown aloft by the inferno.

Nathalie, the swimmer who lost a leg

Nathalie du Toit, the South African swimmer, was only seventeen when she lost her leg in a road accident. She was going to a training session at the swimming pool on her motorbike when a car hit her. Her leg had to be amputated at the knee. At the time she was one of South Africa’s most promising young swimmers. Everybody thought that she would never be able to swim competitively again.

But Nathalie was determined to carry on. She went back into the pool only three months after the accident. And just one year later, at the Commonwalth Games in Manchester, she swam 800 meters in 9 minutes 11:38 seconds and qualified for the final – but not for disabled swimmers, for able-bodied ones! Althought she didn’t win a medal, she still made history.

‘I remember how thrilled I was the first time that I swam after recovering from the operation – it felt like my leg was there. It still does,’ says Nathalie. The water is the gift that gives me back my leg. I’m still the same person I was before the accident. I believe everything happens in life for a reason. You cant go back and change anything. Swimming was my life and still is. My dream is to swim faster than I did before the accident.’
