Posts Servant, Amanuensis & Assistant (to Flamsteed)

Joseph Crosthwait was Flamsteed’s longest serving assistant. Originally from Cumberland, he came to the Observatory in 1708, remaining there until Flamsteed died at the end of 1719. At the time of Flamsteed’s death, the whole of the first volume of his Historia Coelestis Britanica had been printed together with much of the second. Crosthwait saw the second volume through to completion and organised the preparation and printing of the third. This work which was published in 1725 was followed by the Atlas Coelestis in 1729.
