Derek Wyn Taylor was an English journalist, writer, publicist and record producer. He is best known for his role as press officer to the Beatles, with whom he worked in 1964 and then from 1968 to 1970, and was one of several associates to earn the moniker "the Fifth Beatle". Before returning to London to head the publicity for the Beatles' Apple Corps organisation in 1968, he worked as the publicist for California-based bands such as the Byrds, the Beach Boys and the Mamas and the Papas. Taylor was known for his forward-thinking and extravagant promotional campaigns, exemplified in taglines such as "The Beatles Are Coming" and "Brian Wilson Is a Genius". He was equally dedicated to the 1967 Summer of Love ethos and helped stage that year's Monterey Pop Festival.
