English record producer Sir George Martin has died at the age of 90.
His management agency says Martin's family "would like to thank everyone for their thoughts, prayers and messages of support."
British Prime Minister David Cameron quickly paid his condolence to the late legendary music producer, calling George Martin "a giant of music."
Sir George served as producer, collaborator, and mentor to John Lennon, Paul McCartney, George Harrison and Ringo Starr, and guided the band to astounding heights.
He had extensive involvement with each of the band's original albums.
In a career spanning nearly six decades, he produced 30 number-one hit singles in the United Kingdom and 23 number-one hits in the United States.
He was made a Knight Bachelor in 1996.
