The Oxford Dictionary of National Biography (ODNB) is launching an online exhibition to mark the 40th anniversary of the Beatles’ Sgt Pepper’s Lonely Hearts Club Band album.

The exhibition features the lives of over 40 people who appear on the album cover. The iconic cover includes famous individuals such as Karl Marx, Marilyn Monroe and Lewis Carroll.

The collection of biographies is available throughout June and July, alongside around 56,000 articles on influential figures in British history.
