The Symphony No. 99 in E♭ major (Hoboken I/99) is the seventh of the twelve London symphonies (Hoboken numbers 93–104) written by Joseph Haydn. The symphony was written in 1793 in Vienna in anticipation for his second trip to London.
The work was premiered on 10 February 1794 at the Hanover Square Rooms in London, with Haydn directing the orchestra seated at a fortepiano. This concert series featuring Haydn's compositions was organized by his colleague and friend Johann Peter Salomon.[1]
