The astronomer who discovered what stars are made of, Cecilia Payne-Gaposchkin, has been commemorated with an English Heritage blue plaque at her teenage home, 70 Lansdowne Road in Notting Hill.
It was while living at this address that Payne-Gaposchkin won a scholarship to Newnham College, Cambridge.
She later earned a doctorate in astronomy from Harvard and in 1927, she became the youngest astronomer ever to have a star of distinction next to her name in the publication American Men of Science.
Senior historian at English Heritage, Howard Spencer, described her as “a scientist of exceptional brilliance and determination”.
