Memoir and Correspondence of Caroline Herschel (1876) contains the letters and diaries of the celebrated astronomer Caroline Herschel (1750–1848), edited by her niece, Mary Herschel. Caroline was born in Hanover to a musician father and an illiterate mother who did not want her daughter to be educated. However Caroline's brother William, an organist employed in Bath, persuaded their mother to allow Caroline to join him there. She left for England in 1772 to live with William, to whom she remained devoted all of her life. In Bath, William turned towards telescope-making and astronomy, to such effect that in 1781 he discovered the planet Uranus. He was appointed 'the King's astronomer' in 1782, and Caroline, trained by William, continued to work at his side as a scientist in her own right. Between them, they discovered eight comets and raised the number of recorded nebulae from a hundred to 2500.
