Friedrich Nietzsche was born near Leipzig in 1844, the son of a Lutheran clergyman. At 24 he was appointed to the chair of classical philology at Basle University, where he stayed until forced by his health to retire in 1879. Here, he wrote all his literature, including Thus Spake Zarathustra, and developed his idea of the Superman. He became insane in 1889 and remained so until his death in 1900. R. J. Hollingdale translated eleven of Nietzsche's books and published two books about him; he also translated works by, among others, Schopenhauer, Goethe, E. T. A. Hoffmann, Lichtenberg and Theodor Fontane, many of these for Penguin Classics. He was the honorary president of the British Nietzsche Society. R. J. Hollingdale died on 28 September 2001.
