A RUSSIAN interpreter's incredible mission to keep Hitler's teeth safely in a box in the days after his death has been told in English for the first time. 
  
 Yelena Rzhevskaya was 25-years-old when her Soviet unit commander Colonel Gorbushin handed her a burgundy box and told her 'these are Hitler's teeth, if you lose them you are answerable with your head'.

 German radio had announced Hitler killed himself on April 30, 1945, eight days later officials were still trying to get confirmation. 
  
 Theories were circulating that the Fuhrer could have escaped from Berlin and was either hiding in the Alps or en route to South America. 
  
 Yelena's unit was tasked with finding out if the charred teeth discovered in the grounds of the Reich Chancellery were in fact Hitler's. 
  
 Her memoirs have now been published in English for the first time and tell the true story of how the Nazi dictator's death was confirmed.

 Colonlel Gorbushin is said to have told Yelena she was entrusted with the mission because 'we have no safe and as a woman, you're less likely than a man to get drunk and lose them'. 
  
 The memoir tells of trying to trace Hitler's dentists in the war-torn streets of Berlin. 
  
 She wrote: "In places smoke was still rising, the city’s air still filled with the fumes of battle. 
  
 "The barricades, crushed by tank tracks, had yet to be dismantled. Nurses in grey, with white head-scarves bearing a red cross, looked exhausted as, sternly and silently, they went about their duties."

 After hours of searching around the city the team traced the dentist Kathe Heusermann to an apartment near the surgery. 
  
 She managed to find X-rays of Hitler's teeth and his dental records. At 10am the following days she sat down with Russian officers to describe the teeth from memory. 
  
 The dentist recalled gold bridges and crowns attached to the teeth in the box and Hitler's X-rays.

 Yelena wrote: "I really believed that all the nonsensical rumours that Hitler was alive would be swept away and truth would prevail." 
  
 In 2000, Russian authorities put the teeth on display as part of an exhibition to mark the 55th anniversary of the end of the Second World War. 
  
 After the war, Yelena returned to Moscow and became a writer. She died in April last year. ||||| French researchers claim to have put an end to conspiracy theories surrounding the death of Adolf Hitler, after a study of his teeth proved he definitely died after taking cyanide and shooting himself in the head in Berlin in 1945. 
  
 The researchers reached their conclusion after they were given rare access to fragments of Hitler’s teeth which have been held in Moscow since the end of World War II. 
  
 "The teeth are authentic, there is no possible doubt. Our study proves that Hitler died in 1945," said professor Philippe Charlier. 
  
 "We can stop all the conspiracy theories about Hitler. He did not flee to Argentina in a submarine, he is not in a hidden base in Antarctica or on the dark side of the moon," he told AFP news agency. 
  
 The teeth were put on display in 2000 in Moscow as part of an exhibition to mark the 55th anniversary of the end of the war. 
  
 They were back in the news again last month when the memoirs of a Russian interpreter who worked in Berlin in 1945 were published in English for the first time. 
  
 She recounted how she had been tasked with proving Hitler's death by tracking down his dental records in the ruined German capital and seeing if they matched a set of teeth she had been entrusted with - which they did. ||||| In a new study, French scientists analyzed fragments of Adolf Hitler’s teeth to prove that he died in 1945, after taking cyanide and shooting himself in the head. The research, published in the European Journal of Internal Medicine in May 2018, seeks to end conspiracy theories about Adolf Hitler’s death through scientific analysis of the dictator’s teeth and skull. 
  
 “Our study proves that Hitler died in 1945,” lead study author Philippe Charlier told AFP. “The teeth are authentic, there is no possible doubt.” 
  
 Though it’s widely established that Hitler died in his bunker in Berlin, rumors of his escape abound. Their research proves that “he did not flee to Argentina in a submarine, he is not in a hidden base in Antarctica or on the dark side of the moon,” said Charlier. 
  
 In late April 1945, as Soviet forces stormed Berlin, Hitler made plans for his suicide, including testing SS-supplied cyanide pills on his Alsatian, Blondi, and dictating a final will and testament. Two days earlier, Mussolini had been shot by a firing squad and then publicly hung by his feet in a suburban square in Milan, Italy: A similar fate seemed inevitable. 
  
 Late on April 30, the bodies of Hitler and his new wife, Eva Braun, were found in the bunker, with a bullet hole in Hitler’s temple. 
  
 In April 2018, the English publication of the memoirs of a Russian interpreter revealed how she had been entrusted with a set of teeth in 1945, and tasked with cross-checking them against the dictator’s dental records: They matched, and have remained in Russian hands ever since, the Telegraph reported. 
  
 After months of negotiations, Russia’s FSB secret service and the Russian state archives gave the researchers permission to examine a skull fragment and bits of his teeth. The piece of skull had a hole on its left side, consistent with a bullet wound, with black charring around the edges. Though scientists weren’t allowed to take samples from the skull, they noted in the study, its shape seemed “totally comparable” to radiographies of Hitler’s skull taken a year before his death. 
  
 Gruesome pictures of the teeth published in the study show a jaw made mostly of metal. “At the moment of his death,” they wrote in the report, “Hitler had only four remaining teeth.” The few there are are misshapen, brown at the base, and flecked with white tartar deposits. 
  
 The analysis corroborated frequently-cited claims that Hitler was a vegetarian, but could not conclusively prove whether he took cyanide before the gunshot. Bluish deposits on his false teeth, the researchers wrote, suggest a variety of different hypotheses—did some chemical reaction take place between his fake teeth and the cyanide at the moment of death, during his cremation, or while the remains were buried? 
  
 Without taking samples for analysis, it’s hard to say for sure. “We didn’t know if he had used an ampule of cyanide to kill himself or whether it was a bullet in the head. It’s in all probability both,” Charlier said. 
  
 Either way, the study may help finally put to tales of Hitler’s flight to rest, once and for all. |||||

Conspiracy theorists, take note: A new study of teeth and bone stored in Moscow concludes that Hitler really did die in 1945, AFP reports. "The teeth are authentic, there is no possible doubt," says study co-author Philippe Charlier. "Our study proves that Hitler died in 1945. We can stop all the conspiracy theories about Hitler. He did not flee to Argentina in a submarine, he is not in a hidden base in Antarctica or on the dark side of the moon." After much negotiation, History.com notes, the French researchers were granted access by Russia's secret service to analyze the teeth and skull fragment said to be Hitler's. The teeth had been shown in a Moscow exhibition in 2000 marking the 55th anniversary of the end of World War II, the Telegraph recalls. What the study found: The poorly maintained teeth had no remnants of meat fiber (matching Hitler's vegetarian diet) and the skull bit's morphology was "totally comparable" to radiographs of the Fuhrer's skull from 1944. A hole on the skull fragment's left side was likely from a bullet, and bluish deposits on Hitler's false teeth resembled a chemical reaction between cyanide and the metal in Hitler's dentures. "We didn't know if he had used an ampule of cyanide to kill himself or whether it was a bullet in the head," says Charlier. "It's in all probability both." The teeth received attention last month when a Russian interpreter's memoirs, published in English for the first time, recalled how she was handed the teeth in Berlin 1945 and tasked with discovering if they were really Hitler's, the Sun reports.
