Astrid Kirchherr (b. 1938) is a photographer and artist. She invented The Beatles haircut during their early time in Hamburg: she met them at a club when she was dating Klaus Voormann (who later designed the cover to The Beatles' Revolver album), left him for Stuart Sutcliffe, and cut his hair in the familiar mop-top, which John Lennon initially found laughable but eventually adopted, like the others.
