Carl Czerny (German: [karl ˈtʃɛrni]; 21 February 1791 – 15 July 1857) was an Austrian composer, teacher, and pianist of Czech origin whose vast musical production amounted to over a thousand works. His books of studies for the piano are still widely used in piano teaching.

Carl Czerny was born in Vienna (Leopoldstadt) and was baptized in St. Leopold parish. His parents were of Czech origin; his mother was Moravian. His parents spoke the Czech language with him. Czerny came from a musical family: his grandfather was a violinist at Nymburk, near Prague, and his father, Wenzel, was an oboist, organist and pianist. When Czerny was six months old, his father took a job as a piano teacher at a Polish manor and the family moved to Poland, where they lived until the third partition of Poland prompted the family to return to Vienna in 1795.

A child prodigy, Czerny began playing piano at age three and composing at age seven. His first piano teacher was his father, who taught him mainly Bach, Haydn and Mozart. He began performing piano recitals in his parents' home. Czerny made his first public performance in 1800 playing Mozart's Piano Concerto No. 24 in C minor.

In 1801, Wenzel Krumpholz a Czech composer and violinist scheduled a presentation for Czerny at the home of Ludwig van Beethoven. Beethoven asked Czerny to play his Pathétique Sonata and Adelaide. Beethoven was impressed with the 10-year-old and accepted him as a pupil. Czerny remained under Beethoven's tutelage until 1804 and sporadically thereafter. He particularly admired Beethoven's facility at improvisation, his expertise at fingering, the rapidity of his scales and trills, and his restrained demeanour while performing.

Czerny's autobiography and letters give many important references to Beethoven during this period. Czerny was the first to report symptoms of Beethoven's deafness, years before the matter became public: "I also noticed with that visual quickness peculiar to children that he had cotton which seemed to have been steeped in a yellowish liquid, in his ears."
