Beethoven's previous piano sonata, popularly known as Les Adieux, was composed almost five years prior to Op. 90. Beethoven's autograph survives and is dated August 16. The sonata was published almost a year later, in June 1815, by S. A. Steiner, after a few corrections were made by Beethoven. Beethoven's letter to Prince Moritz von Lichnowsky, sent in September 1814, explains Beethoven's dedication:
