Page "George Biddell Airy" Paragraph 14

In June 1846, Airy started corresponding with French astronomer Urbain Le Verrier over the latter's prediction that irregularities in the motion of Uranus were due to a so-far unobserved body.

Aware that Cambridge Astronomer John Couch Adams had suggested that he had made similar predictions, on 9 July Airy entreated James Challis to undertake a systematic search in the hope of securing the triumph of discovery for Britain.

Ultimately, a rival search in Berlin by Johann Gottfried Galle, instigated by Le Verrier, won the race for priority.

Though Airy was " abused most savagely both by English and French " for his failure to act on Adams's suggestions more promptly, there have also been claims that Adams's communications had been vague and dilatory and further that the search for a new planet was not the responsibility of the Astronomer Royal.
