One of the greatest composers of all times, Ludvig van Beethoven was born in Bonn in 1770, the eldest son of a singer in the Kapelle of the Archbishop-Elector of Cologne and grandson of the Archbishop's Kapellmeister. Beethoven moved in 1792 to Vienna, where he had some lessons from Haydn and others, quickly establishing himself as a remarkable keyboard-player and original composer. By 1815 increasing deafness made Beethoven's public performance impossible and accentuated Beethoven's existing eccentricities of character, patiently tolerated by a series of rich patrons and his royal pupil the Archduke Rudolph. Beethoven did much to enlarge the possibilities of music and widen the horizons of later generations of composers.
