High Quality Content by WIKIPEDIA articles! Peter Andreas Hansen (December 8, 1795 March 28, 1874) was a Danish astronomer, was born at Tønder, Schleswig. The son of a goldsmith, he learned the trade of a watchmaker at Flensburg, and exercised it at Berlin and Tønder, 1818 1820. He had, however, long been a student of science; and Dr Dircks, a physician practising at Tønder, prevailed with his father to send him in 1820 to Copenhagen, where he won the patronage of H.C. Schumacher and attracted the personal notice of King Frederick VI. The Danish survey was then in progress, and he acted as Schumacher's assistant in work connected with it, chiefly at the new observatory of Altona, 1821 1825. Thence he passed on to Gotha as director of the Seeberg observatory; nor could he be tempted to relinquish the post by successive invitations to replace F.G.W. Struve at Dorpat in 1829, and F.W. Bessel at Königsberg in 1847. The problems of gravitational astronomy engaged the chief part of Hansen's attention.
