John Flamsteed.

Bust of John Flamsteed in the Museum of the Royal Greenwich Observatory
'John Flamsteed' (
19 August,
1646 -
31 December,
1719) was an
English astronomer.
Flamsteed was born in
Denby,
Derbyshire,
England, and was educated at
Derby School and
Jesus College, Cambridge. He was ordained deacon and was preparing to take up a living in Derbyshire, when he was invited to London. On
4 March 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 eclipses of
1666 and
1668. He was responsible for several of the earliest recorded sightings of the
planet Uranus, which he mistook for a
star and catalogued as 34
Tauri. The first of these was in December, 1690, which remains the earliest known sighting of Uranus by an astronomer.
On
August 16 1680 Flamsteed catalogued a star, 3 Cassiopeiae, that later astronomers were unable to corroborate. Three hundred years later, the American astronomical historian
William Ashworth suggested that what Flamsteed may have seen was the most recent supernova in the galaxy's history, an event which would leave as its remnant the strongest radio source outside of the solar system, known in the
third Cambridge (3C) catalogue 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, the President of the
Royal Society at the time. Flamsteed was refusing to publish work that had been commissioned by 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 many 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 designations.
In
1725 Flamsteed's own version of ''Historia Coelestis Britannica'' was published. This contained Flamsteed's observations, and included a catalogue of 2,935 stars to much greater accuracy than any prior work. This was considered the first significant contribution of the Greenwich Observatory.
Honours
★ Elected a Fellow of the
Royal Society in
1676.
★
Flamsteed crater on the
Moon is named after him.
★ Numerous Schools and colleges in
Derbyshire have been named after him in his honour. The Science block at
John Port School is named Flamsteed in recognition of his work for Science.
John Flamsteed Community School in
Denby carries his name. Flamsteed House at the Ecclesbourne School in
Duffield is also named after him.
