Book excerpt: Through a series of case studies from the mid-eighteenth century to the start of the twenty-first, this collection of essays considers the historical insights that ethno/auto/biographical investigations into the lives of individuals, groups and interiors can offer design and architectural historians. Established scholars and emerging researchers shed light on the methodological issues that arise from the use of these sources to explore the history of the interior as a site in which everyday life is experienced and performed, and the ways in which contemporary architects and interior designers draw on personal and collective histories in their practice. Historians and theorists working within a range of disciplinary contexts and historiographical traditions are turning to biography as means of exploring and accounting for social, cultural and material change - and this volume reflects that turn, representing the fields of architectural and design history, social history, literary history, creative writing and design practice. Topics include masters and servants in eighteenth-century English kitchens; the lost interiors of Oscar Wilde's 'House Beautiful'; Elsa Schiaparelli's Surrealist spaces; Jean Genet, outlaws, and the interiors of marginality; and architect Lina Bo Bardi's 'Glass House', S?Paulo, Brazil.
