The Piano Concerto No. 5 in E-flat major, Op. 73, known more commonly as the Emperor Concerto, was Beethoven's last piano concerto. It was written between 1809 and 1811 in Vienna, and was dedicated to Archduke Rudolf, Beethoven's patron and pupil. Like many nicknames in music, the epithet of "Emperor" for this concerto was not Beethoven's. Rather, it was coined by Johann Baptist Cramer, the English publisher of the concerto.
