Family of British astronomers, including Sir William Herschel (1738-1822), who discovered Uranus (1781) and cataloged more than 800 double stars and 2,400 previously unknown nebulae and other deep-sky objects. His sister Caroline Herschel (1750-1848) assisted in his work and discovered numerous comets. His son Sir John Frederick William Herschel (1792-1871) cataloged nearly 2,000 more deep-sky objects and conducted notable research on light, photography, and astrophysics.

2. (Biography) Sir John Frederick William. 1792–1871, British astronomer. He discovered and catalogued over 525 nebulae and star clusters
3. (Biography) his father, Sir (Frederick) William, original name Friedrich Wilhelm Herschel. 1738–1822, British astronomer, born in Germany. He constructed a reflecting telescope, which led to his discovery of the planet Uranus (1781), two of its satellites, and two of the satellites of Saturn. He also discovered the motions of binary stars

Family of British astronomers. Sir William Herschel (1738-1822) discovered Uranus (1781) and cataloged more than 800 binary stars and 2,500 nebulae. His sister Caroline Herschel (1750-1848) discovered 8 comets and several nebulae and star clusters, and published a star catalog in 1798. His son Sir John Frederick William Herschel (1792-1871) discovered 525 nebulae and pioneered celestial photography. See Note at infrared.
Biography Both William and Caroline Herschel began their professional careers as musicians. They were born in Germany and later moved to England, where Caroline became a soprano soloist in performances conducted by her brother. William's background in music theory spurred him to study mathematics and astronomy, and he taught his sister in turn. Each produced a string of important discoveries. William was the first astronomer to study binary stars. His careful observations and his skill at mapping the stars led him to discover the planet Uranus in 1781. It was the first new planet to be discovered since ancient times. He further discovered two satellites of Uranus, Titania and Oberon (1787), and two of Saturn, Mimas and Enceladus (1789-1790). King George III appointed William his Astronomer Royal in 1787, and Caroline was made his assistant. Caroline observed her first comet in 1786 and later discovered seven others, as well as nebulae and star clusters. After her brother's death in 1822, Caroline reorganized and published his catalog of nebulae. She also continued her own observations up to the end of her life.
