David Edward Williams, known professionally to millions as David Walliams, stands as one of the most versatile and recognisable figures in British entertainment, a man whose career has spanned comedy, acting, children's literature, and television judging. Born on 20 August 1971 in Merton, London, he first captured the public imagination through his groundbreaking partnership with Matt Lucas on the BBC sketch show Little Britain. The series, which ran from 2003 to 2006, became a cultural phenomenon, introducing audiences to a gallery of unforgettable characters such as the loudly-spoken Lou and Andy and the delusional Vicky Pollard. Walliams and Lucas followed this success with the airport mockumentary Come Fly with Me in 2010, further cementing their status as a formidable comedy duo known for their chameleon-like transformations and fearless character work.

While his comedy career flourished, Walliams became a household name for a new generation of viewers through his long-running role as a judge on the ITV talent competition Britain's Got Talent, a position he held with distinction from 2012 to 2022. His presence on the panel, alongside figures like Simon Cowell, Amanda Holden, and Alesha Dixon, earned him multiple National Television Awards and made him a beloved fixture in British living rooms. In addition to this mainstream exposure, he wrote and starred in the BBC sitcom Big School (2013–2014), took on the role of Tommy Beresford in the 2015 BBC drama series Partners in Crime alongside Jessica Raine, and showcased his solo talents in the sketch series Walliams & Friend. His charitable endeavours are equally notable, with his swims across the English Channel, the Strait of Gibraltar, and the River Thames raising millions for the BBC's Sport Relief campaign, efforts that were recognised in 2017 when he was appointed Officer of the Order of the British Empire (OBE) for services to charity and the arts.

Beyond the screen, Walliams has forged an extraordinary second career as a children's author, a path he began in 2008 after signing a contract with HarperCollins. His novels, which have sold over fifty million copies worldwide and been translated into fifty-three languages, have earned him comparisons to the legendary Roald Dahl and the title of "the fastest-growing children's author in the UK." Books such as Gangsta Granny, The Boy in the Dress, and Demon Dentist have delighted young readers and have been adapted for television, with Walliams often appearing in these productions. However, his literary empire faced a dramatic turn in 2025 when HarperCollins ended their publishing contract with him following an internal investigation into allegations of inappropriate behaviour and harassment towards junior female staff. Despite this controversy, Walliams remains a towering figure in British popular culture, his legacy defined by a remarkable range of achievements that span low comedy, high drama, and the hearts of millions of children.
