Charles Edward Horn (21 June 1786 – 21 October 1849) was an English composer and singer.Horn was born in St Martin-in-the-Fields, London, to Charles Frederick Horn and his wife, Diana Dupont. He was the eldest of their seven children. His father taught him music; he also took music lessons briefly in 1808 from singer Venanzio Rauzzini in Bath, Somerset. Horn made his singing debut on 26 June 1809 with a performance in the comic opera Up All Night, or the Smuggler's Cave (words by Samuel James Arnold and music by Matthew Peter King) at Lyceum Theatre, London. Horn continued singing, including a well-received turn in 1814 as Seraskier in Stephen Storace's The Siege of Belgrade. He achieved prominence with his portrayal of Caspar in the English version of Carl Maria von Weber's Der Freischütz in 1824.
