Profession: Astronomer, Mathematician and Physicist
Why Famous: Edmund Halleys' reputation mainly rests on his discovery of the orbit of Halley's Comet, named after him but he was widely involved in a number of scientific endeavors.
Halley was educated at Queens' College, Oxford where he was influenced by the work of Astronomer Royal John Flamsteed's work to catalog the starts of the northern hemisphere.
In 1676 Halley began a voyage to St Helena in the southern hemisphere and had catalogued more than 300 stars by his return in 1678, publishing it later that year. As a result he was elected a fellow of the Royal Society.
Halley was instrumental in bringing Issac Newton's discoveries on planetary motion to publication, editing and overseeing the printing of Newton's "Principia" in 1687.
IN 1705 Halley published his own work A Synopsis of the Astronomy of Comets, in which he detailed the orbits of known comets and made the case that 3 were actually the same comet returning. He also sucessfully predicted its return in 1758.
In 1720 Halley was appointed Astronomer Royal at Greenwich.
