Scientists have identified a mummified body found in a Swiss churchyard as the great-great-great-great-great-great-grandmother of British Foreign Secretary Boris Johnson.
The body of an apparently wealthy woman was found decades ago during renovations on the Barfuesser Church in Basel. There was no gravestone, and her identity was a mystery.
Basel’s Natural History Museum said Thursday that by matching DNA extracted from the mummy’s toe with a living descendant, its experts led an international team that identified the woman as Anna Catharina Bischoff, a member of a prominent Basel family who died in 1787 at the age of 68.
The BBC reported that Bischoff was likely poisoned by mercury, then a common treatment for syphilis, which she may have acquired while tending to patients with the sexually transmitted disease.
Bischoff’s daughter married Christian Hubert Baron Pfeffel von Kriegelstein, and their descendants include Britain’s foreign minister, Alexander Boris de Pfeffel Johnson.
Johnson tweeted that he was “very excited to hear about my late great grand ‘mummy’ – a pioneer in sexual health care. Very proud.”
The foreign secretary’s father, author Stanley Johnson, said he was “totally thrilled.”
Natural History Museum anthropologist Gerhard Hotz said a team of more than 40 people worked to identify the mystery woman.
“It was a risky project,” he said. “We didn’t know where we were going and whether we would gain anything. We had so much luck. And then entered Boris Johnson — what more do you want?”
