Alan Aldridge, the iconic illustrator for the best-selling book The Beatles Illustrated Lyrics, as well as for classic albums by Elton John and The Who, has passed away at the age of 73.

After working for the Sunday Times Magazine and Penguin Books, he started his own art firm, INK, in association with the Beatles’ Apple Corps.

Born in London on June 1, 1943, Aldridge started his design career at the Sunday Times Magazine before moving to Penguin Books, where he rose through the ranks and ultimately became the company’s art director. By the late ’60s, he’d started his own firm, INK, which opened an association with the Beatles’ Apple Corps.

By the mid-’70s, he designed the cover for the Who’s  A Quick One, produced the artwork on Elton John‘s Captain Fantastic and the Brown Dirt Cowboy LP, and filled the Beatles’ Illustrated Lyrics with his signature style.

Beyond the world of rock n’ roll, Aldridge lent his talents to multiple bestselling books and created the Hard Rock Cafe’s logo.

The details of Aldridge’s death have not been made public. News of his passing is confirmed by his daughter Lily, who shared her sadness in an Instagram post that includes the farewell, “thank you for the years of magic.”
