Mary Somerville (née Fairfax, formerly Greig; 1780–1872) was a Scottish scientist, writer, and polymath. She studied mathematics and astronomy, and in 1835 she and Caroline Herschel were elected as the first female Honorary Members of the Royal Astronomical Society. In John Stuart Mill's 1866 mass petition to the UK Parliament to grant women the right to vote, the first signature on the petition was Somerville's, which she signed before the age of 86.
