Christopher Jarvis Haley Hogwood was an English conductor, harpsichordist, writer, and musicologist. Founder of the early music ensemble the Academy of Ancient Music, he was an authority on historically informed performance and a leading figure in the early music revival of the late 20th century.

The Academy of Ancient Music (AAM) is a British period-instrument orchestra based in Cambridge, England. Founded by harpsichordist Christopher Hogwood in 1973, it was named after an 18th-century organisation of the same name. The musicians play on either original instruments from the period when the music was composed or modern copies of such instruments. They generally play Baroque, Classical, and sometimes Romantic music, though they have also played some new compositions for baroque orchestra in recent years.
