In a sense Sadie Williams, the youngest daughter of Ralph Steadman and his late, second wife, Anna, has been involved in her father’s professional life since she was a small child. It was his illustrated children’s books that were read to her at bedtime. She spent many a long afternoon in bookshops at his book launch signings and looked on as film crews and photographers arrived at her home to interview her father. She was taken along on many of the business trips her parents were lucky enough to enjoy. These included the trips to vineyards across Europe for Oddbins, the visit to Italy where Steadman researched his illustrated book I Leonardo, and the holiday to Hawaii in 1980 with Hunter S. Thompson, which would result in the novel The Curse of Lono. Her life has always been interwoven into the tapestry of her father’s work.

In 2010, the Steadman family formed Ralph Steadman Art Collection with the hope of cataloguing his extensive archive, since he famously shies away from selling his originals. It was then that Sadie formally began working with her father’s artwork. Over the years she has organized and established a museum-standard archive for the works, a project which is still in progress. She has collaborated with publishers and international brands to coordinate projects such as the Breaking Bad DVD artworks, the partnership with urban fashion brand, Vans, and the illustrations for the Shane McGowan: Crock of Gold documentary.

Sadie has established a social-media presence for Ralph on Facebook, Twitter, and Instagram and manages his online shop and websites, designing products, packaging, and even dispatching most of the orders herself. She investigated the new, emerging NFT markets and in 2022 launched Ralph’s art on objkt.com and niftygateway.com, always eager to expose new audiences to her father’s artwork, initiating collaborations with other artists and taking part in open forums on art and its place in the virtual world.

In 2012 after the Cartoon Museum curated Steadman@77, a full retrospective of the artist’s work, which was booked to travel to New York for exhibition, Sadie began searching for funding to tour the show throughout America, succeeding in taking it to Washington DC, San Francisco, Eugene, Oregon, and Lexington, Kentucky before it finally had to be returned to the UK because of the Covid pandemic.

That work now continues in two brand-new exhibitions, Ralph Steadman: And Another Thing…, a new incarnation of the retrospective, currently touring museums in the USA until 2027, and Ralph Steadman: Inkling, an exhibition at the Historic Dockyard, Chatham, which opened in September 2024. A new collaboration with F1 driver Lewis Hamilton’s lifestyle brand, +44 went live in November 2025.
