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 cover), 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.
