Prue - with husband Don Anderson - established Anderson O'Day in 1971. In 1986, Prue opened Anderson O'Day Gallery in Portobello Road, London and over the next ten years it became known as a significant place for discovering emerging talent.
Prue also worked as an independent art advisor to corporations building significant collections. Major commissions included collaborations with Sol LeWitt and Norman Foster at Tower Place, Rebecca Warren and Renzo Piano at Central Saint Giles, and HM Treasury Whitehall.
Near the turn of the new millennium she co-founded The Wonderful Fund, a five-year project to develop a collection of contemporary art marking this milestone, on behalf of 16 fund members who enjoyed shared ownership of the works.
Prue chaired The Showroom
for seven years to 2013, guiding its relocation to a central London space and achieving financial stability for the organisation. From 2009 to 2013, she mentored Glasgow Museum of Art
for the Art Fund International purchasing scheme. She has been a guest lecturer and external examiner on the Sotheby's Institute MA, and was also a regular contributor to Professional Development courses at London art schools. Prue is on the Council of the ICA London
, the Gifts and Acquisitions Committee at The Hepworth
, Wakefield, an active supporter of Artangel
