John Couch Adams FRS (5 June 1819 – 21 January 1892) was a British mathematician and astronomer. Adams was born in Laneast, near Launceston, Cornwall, and died in Cambridge. The Cornish name Couch is pronounced "cooch".
His most famous achievement was predicting the existence and position of Neptune, using only mathematics. The calculations were made to explain discrepancies with Uranus's orbit and the laws of Kepler and Newton. At the same time, but unknown to each other, the same calculations were made by Urbain Le Verrier. Le Verrier would assist Berlin Observatory astronomer Johann Gottfried Galle in locating the planet on 23 September 1846, which was found within 1° of its predicted location, a point in Aquarius. (There was, and to some extent still is, some controversy over the apportionment of credit for the discovery; see Discovery of Neptune.)
He was Lowndean Professor at the University of Cambridge for thirty-three years from 1859 to his death. He won the Gold Medal of the Royal Astronomical Society in 1866. In 1884, he attended the International Meridian Conference as a delegate for Britain.
A crater on the Moon is jointly named after him, Walter Sydney Adams and Charles Hitchcock Adams. Neptune's outermost known ring and the asteroid 1996 Adams are also named after him. The Adams Prize, presented by the University of Cambridge, commemorates his prediction of the position of Neptune. His personal library is now in the care of Cambridge University Library.

Famous quotes containing the words john, couch and/or adams:
“I do not wish to see John ever again,—I mean him who is dead,—but that other, whom only he would have wished to see, or to be, of whom he was the imperfect representative. For we are not what we are, nor do we treat or esteem each other for such, but for what we are capable of being.”
—Henry David Thoreau (1817–1862)
“Where the bee sucks, there suck I,
In a cowslip’s bell I lie;
There I couch when owls do cry.
On the bat’s back I do fly
After summer merrily.
Merrily, merrily shall I live now,
Under the blossom that hangs on the bough.”
—William Shakespeare (1564–1616)
“Positively I sit here, and look at Europe sink, first one deck disappearing, then another, and the whole ship slowly plunging bow-down into the abyss; until the nightmare gets to be howling. The Roman Empire was a trifle to it.”
—Henry Brooks Adams (1838–1918)
