John Flamsteed, ( 19 August , 1646 - 31 December , 1719 ) was an English Astronomer . He was born in Denby , Derbyshire , England . He was ordained deacon and was preparing to take up a living in Derbyshire, when he was invited to London. On March 4 1675 he was appointed by royal warrant "The King's Astronomical Observator" — the first British Astronomer Royal , with an allowance of £100 a year. In June 1675, another royal warrant provided for the founding of the Royal Greenwich Observatory , and Flamsteed laid the foundation stone in August. In February 1676 , he was admitted a Fellow of the Royal Society , and in July, he moved into the Observatory where he lived until 1684 , when he was finally appointed priest to the parish of Burstow , Surrey . He held that office, as well as that of Astronomer Royal, until his death. He is buried at Burstow. Flamsteed accurately calculated the Solar Eclipse s of 1666 and 1668 . He was responsible for one of the earliest recorded sightings of the Planet Uranus , which he mistook for a Star and catalogued as 34 Tauri . On as 3C 461 and commonly called Cassiopeia A by astronomers. Because the position of "3 Cassiopeiae" does not precisely match that of Cassiopeia A, and because the expansion wave associated with the explosion has been worked backward to the year 1667 and not 1680 , some historians feel that all Flamsteed may have done was incorrectly note the position of a star already known. Flamsteed is also remembered for his conflicts with Isaac Newton , then President of the Royal Society , who attempted to steal some of Flamsteed's findings for his own work. Newton tricked Flamsteed through an edict from the King, and in 1712 Newton and Edmond Halley published a preliminary version of Flamsteed's ''Historia Coelestis Britannica'' without crediting the author. Some years later, Flamsteed managed to buy most copies of the book, and publicly burnt them in front of the Royal Observatory. However, the numerical star designations in this book are still used and are known as Flamsteed Designation s. In 1725 Flamsteed's own version of ''Historia Coelestis Britannica'' was published. This contained Flamsteed's observations, and included a catalogue of almost 3,000 stars to much greater accuracy than any prior work. This was considered the first significant contribution of the Greenwich Observatory. HONOURS
