This is the chapter on 16th century Danish astronomer Tycho Brahe from Sir Robert S. Ball's Great Astronomers, second edition, which begins: "The most picturesque figure in the history of astronomy ... Tycho Brahe was alike notable for his astronomical genius and for the extraordinary vehemence of a character which was by no means perfect. His romantic career as a philosopher, and his taste for splendour as a Danish noble, his ardent friendships and his furious quarrels, make him an ideal subject for a biographer, while the magnificent astronomical work which he accomplished has given him imperishable fame.
