Sir George Biddell Airy (1801-92)

Within the Caird Library’s collection of rare books is the personal library of the seventh Astronomer Royal, Sir George Biddell Airy. It features a plethora of scientific and astronomical research, as well as some of the Library’s most historically significant works such as Copernicus’s influential De revolutionibus orbium coelestium and Flamsteed’s controversial Historiae coelestis, which was published without his consent.

Working in astronomy has always been a challenge for women but somehow they’ve managed to contribute in their own way, whether it’s observing directly themselves or recording and analysing data from other astronomers. Others contributed by writing popular books and developing education materials to share the subject with others. Their work has long been overshadowed by their male counterparts but in this blog I’d like to focus on one particular female astronomer who worked here at the Royal Observatory, Greenwich, during the 1890s and whose story really encapsulates the struggles faced by women in astronomy at the time.
