Caroline Herschel

Caroline was seventeen when she arrived in England. She had been very close to William and must have been devastated when he left home - particularly as her mother, who really only had time for her oldest son, Jacob, neglected the child. Caroline was treated as a servant: she contracted typhoid as a child, as a result of which her growth was stunted; she was tiny, just a little over four feet tall. But things took a turn for the better when William came back to Hanover and rescued her. He taught her to play music and to sing - so well that she was offered a post with an opera company in Birmingham.

But by this time, Caroline and William were both becoming fascinated with astronomy. (I've noticed that there's often a connection between music and science, though I don't know enough about either to understand why this is.) William learnt how to grind and polish lenses, and built increasingly large telescopes which he used to sweep the night sky. Caroline was initially his recorder and note taker, but she progressed to making her own observations.
