Anne Isabella Milbanke

Anne Isabella Milbanke, often called Annabella, was the wife of the famous British Romantic poet Lord Byron. Born into an aristocratic family, she was known for her mathematical aptitude, which Byron initially nicknamed her "the princess of parallelograms."

Their marriage, which took place in January 1815, was short-lived and troubled. Annabella accused Byron of abuse, while he found her unimaginative. Their daughter, Augusta Ada Byron, was born in December 1815. By January 1816, Annabella left Byron, and they legally separated. Byron then left England permanently, never to see his daughter again. Annabella Milbanke's legacy is largely tied to her daughter, Ada Lovelace, who became a pioneering mathematician and is celebrated as the first computer programmer.12
