Edward Benson Powell was an American arranger, orchestrator and composer, who served as Alfred Newman's musical lieutenant at 20th Century Fox film studios for over three decades. His contributions to the scores of 400 films culminated in the canon of widescreen Rodgers and Hammerstein musicals of the late 1950s, for which his arrangements, such as the extended "Carousel Waltz", continue to be revived in concerts and proms, as well as live-to-classic pictures. Powell was occasionally credited as Ed or without the middle initial, but his friends invariably called him Eddie.
