"I will miss this wonderful man but will always cherish the fond memories I have of him."
Freeman's photographs first made the covers of the quartet's "Meet the Beatles!" and "Beatles for Sale" albums, which came out at the height of the Beatlemania that swept the world in the mid-1960s.
For the slightly comical cover of "Help!", John Lennon, McCartney, George Harrison and Ringo Starr were meant to spell out the title in flag semaphore. Freeman decided to rearrange their arm positions to give the cover a better look, with the group spelling out gibberish in the end - but it hardly hurt sales.
On "Rubber Soul", the slightly distorted look of the band's portrait foreshadowed the psychodelic era that was to define both the band's later sound and the late 1960s.
Freeman went on to photograph other pop culture icons such as Andy Warhol and Muhammed Ali.
