The Piano Concerto No. 1 in E minor, Op. 11, is a piano concerto written by Frédéric Chopin in 1830, when he was twenty years old. It was first performed on 12 October of that year, at the Teatr Narodowy in Warsaw, Poland, with the composer as soloist, during one of his "farewell" concerts before leaving Poland.

Friedrich Wilhelm Michael Kalkbrenner, also known as Frédéric Kalkbrenner, was a pianist, composer, piano teacher and piano manufacturer. German by birth, Kalkbrenner studied at the Conservatoire de Paris, starting at a young age and eventually settled in Paris, where he lived until his death in 1849. Kalkbrenner composed more than 200 piano works, as well as many piano concertos and operas.
