Abstract

Edmond Halley was born on November 8, 1656 in Haggerton, UK. He was a major English, astronomer, mathematician, and physicist, who was also interested in demography, insurance mathematics (Actuarial Methods), geology, oceanography, geography, and navigation. Moreover, he was considered an engineer and a social statistician whose life was filled with the thrill of discovery. In 1705, he reasoned that the periodic comet—now known as Halley's comet—that appeared in 1456, 1531, 1607, and 1682, was the same comet that appears every 76 years, and accurately predicted that it would appear again in December 1758. His most notable achievements were his discoveries of the motion of stars, which were then considered fixed, and a scheme for computing the motion of comets and establishing their periodicity in elliptical orbits. Edmond Halley died on January 14, 1742 in Greenwich, UK.
