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".[3] 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.[4]
