The work was dedicated to Count Franz von Oppersdorff, a relative of Beethoven's patron, Prince Lichnowsky. The Count met Beethoven when he traveled to Lichnowsky's summer home where Beethoven was staying. Von Oppersdorff listened to Beethoven's Symphony No. 2 in D Major, and liked it so much that he offered a great amount of money for Beethoven to compose a new symphony for him. Beethoven undertook the new work during the summer of 1806 and completed it in roughly a month, while working on the Fourth Piano Concerto and revising his opera Fidelio, then still known as Leonore. The dedication was made to "the Silesian nobleman Count Franz von Oppersdorf". Hector Berlioz was so enamoured of the symphony's 2nd movement that he claimed it was the work of the Archangel Michael, and not that of a human.
