Edmond Halley (1656-1742) was an English astronomer, geophysicist, and mathematician known for his significant contributions to the fields of astronomy and mathematics. He was born on November 8, 1656, in Haggerston, London, England, and he passed away on 14 January 1742.
Halley is most famous for predicting the return of a comet that later became known as Halley's Comet. He made this prediction based on the observations of comets in historical records and calculated their orbits. His accurate prediction of the comet's return in 1758, after his own lifetime, cemented his reputation as an astronomer.
In addition to his work on comets, Halley also conducted research on tides, magnetism, and the Earth's magnetic field. He was one of the early advocates for the theory of universal gravitation proposed by Sir Isaac Newton and played a key role in publishing Newton's "Principia Mathematica."
Halley's work in these areas made him a prominent figure in the scientific community of his time, and his name is immortalized through Halley's Comet, which returns to the inner solar system approximately every 76 years.
