'''Piano Concerto No. 1 in C major''', Op. 15, was written during 1796 and 1797. Dedicated to his pupil Countess of Bratislava,Frederik Federmayer: Rody starého Pre\u0161porka. Bratislava/Pressburg/Pozsony 2003 Anna Louise Barbara ("Babette") Keglevics, its first performance was in Prague in 1798, with Beethoven himself playing the piano.''Zweite Beethoveniana: Nachgelassene Aufsätze'', p. 512, Bibliothek der deutschen Literatur, Gustav Nottebohm, Verlag Peters, 1887.
Although this was Beethoven's first piano concerto to be published, it was, in fact, his third attempt at the genre, following an unpublished piano concerto in E-flat major (not to be confused with Beethoven's more famous "Emperor" concerto, also in E-flat) and the Piano Concerto No. 2, published after Piano Concerto No. 1 (in 1801) but composed almost ten years earlier.
