Queen Elizabeth II — at 92 — shared her first ever Instagram post Thursday while visiting London's Science Museum.

For her introductory post, she shared a letter from the Royal Archives that was sent by mathematician and computer pioneer Charles Babbage to Queen Victoria's husband and Queen Elizabeth's great-great-grandfather, Prince Albert.

"Today, as I visit the Science Museum I was interested to discover a letter from the Royal Archives, written in 1843 to my great-great-grandfather Prince Albert," she wrote in her post on the official @TheRoyalFamily account. In the letter, Babbage told Queen Victoria and Prince Albert about his invention, the "Analytical Engine" — one of his greatest achievements.

"Today, I had the pleasure of learning about children's computer coding initiatives and it seems fitting to me that I publish this Instagram post, at the Science Museum which has long championed technology, innovation and inspired the next generation of inventors," she wrote.

She signed the post "Elizabeth R."
