Louisa Buck is the only daughter of the late Sir Antony BuckMPQC by his first wife, Judy Grant, from whom he was divorced after 34 years. His marriage to his second wife, Spanish fashion designer, Bienvenida Pérez Blanco, who was 30 years younger than him, ended in scandal, when she admitted adultery with Sir Peter Harding, the British Chief of the Defence Staff, and sold her story to the News of the World for £150,000. Prior to this, Sir Antony had seemed "the epitome of middle-ranking orthodox Tory establishment achievement": he was Conservative Party MP for Colchester for 30 years, and under Edward Heath, Parliamentary Under-Secretary of State for Defence . Louisa Buck said at her father's remembrance service that he had a "lifelong loathing of pomposity, wicked irreverence and dogged loyalty, even when it was against his own interests".
She writes on contemporary art for a number of different journals, as well as making television appearances. Her first book, Moving Targets 2, gives profiles of the artists, curators, collectors, critics and galleries who contribute to the "best and most challenging art that is being made in Britain". Profiles of artists include Damien Hirst, Tracey Emin, Chris Ofili and Cornelia Parker; critics include Adrian Searle, curators, Sir Nicholas Serota and dealers, Jay Jopling of the White Cube gallery. In 2000, she criticised the Stuckists artists, "I saw the last Stuckists exhibition and some of the work was just plain cack... There may be a lot of boring conceptual work but to have a grumpy reactionary movement against it is just daft." In 2004, she compiled a report for the Arts Council, Market Matters: The dynamics of the contemporary art market. She quoted Thomas Hoving, former Director of the Metropolitan Museum of Art, "Art is sexy! Art is money-sexy! Art is money-sexy-social-climbing-fantastic!", a description she elsewhere says has "never... seemed more apt" In 2005, she was a member of the Turner Prize jury, which awarded the prize to Simon Starling, whose main exhibit Shedboatshed was a wooden shed he had converted into a boat, sailed down the River Rhine and then turned back into the original shed.
