Sir George Henry Martin, the world's most famous record producer and oft dubbed the "fifth Beatle", has died at age 90.
Martin signed the Beatles to Parlophone Records in 1962 after Decca famously had turned them down. He went on to produce all but one of their albums. He became and remained one of the most influential producers in popular music history and his reputation stretched well beyond his astonishing career with the Fab Four.
In his early years he produced classical recordings for EMI, as well a number of notable MOR and comedic stars of the era such as Matt Monro, The Goons, and Peter Sellers.
