Sculpture of the astronomer William Herschel (1738-1822) with his sister Caroline Lucretia (1750-1848). Originally a musician, he designed and built high-quality reflector telescopes, achieving world fame in 1781 with the discovery of the planet Uranus, the first to be found telescopically. With the collaboration of Caroline he made systematic studies of the stellar universe, producing a catalogue of double stars in 1782. Caroline Herschel at first assisted her elder brother with his musical activities but became more involved in astronomy, discovering eight comets between 1786 and 1797. For her astronomical work she was awarded the Gold Medal of the Royal Astronomical Society in 1828. Situated in the garden of their house in Bath, now the Herschel Museum, the sculpture was created by Vivien Mousdell in 1988 to commemorate the 250th anniversary of William Herschel's birth.
