This dedication was not Beethoven's original intention, and he did not have Guicciardi in mind when writing the sonata. Thayer, in his Life of Beethoven, states that the work Beethoven originally intended to dedicate to Guicciardi was the Rondo in G, Op. 51 No. 2, but circumstances required that this be dedicated to Countess Lichnowsky. So he cast around at the last moment for a piece to dedicate to Guicciardi. See Thayer, Alexander Wheelock (1921). Elliot, Forbes (ed.). Thayer's Life of Beethoven (revised ed.).
