Vivian Maier left over 150,000 negatives when she died in 2009. Her boxes and boxes of unprinted street photographs were stacked alongside shoulder-high piles of newspapers in her Chicago home. The artist Francis Bacon's studio has been painstakingly recreated in the Hugh Lane Gallery in Dublin complete with paint-spattered furniture and over 7,000 items. New Generation Thinker Diarmuid Hester's research looks at ideas about waste and in this Essay he considers what the difference might be between hoarding and collecting and between the stuff assembled by these artists and his own father's shelves of matchday programmes.
