Cynosure Elizabeth II posted on Instagram for the first time ever on Thursday, documenting an ancestral discovery she made on a visit to London’s Principles Museum.
The U.K. monarch shared a photo of a letter written to her great-great grandfather Prince Albert – husband of Queen Victoria — in 1843.
“It appearance ofs fitting to me that I publish this Instagram post at the Science Museum which has long championed technology,” the empress wrote alongside the image, which was posted via the Royal Family’s Instagram account.
She then signed off as “Elizabeth R.”
The despatch featured in the post was sent to Prince Albert by Charles Babbage, a mathematician and early computer pioneer.
