This chapter explores the centrality of biography and autobiography to Woolf’s reading and writing life, and to her cultural milieu, in which experiments in life-writing were a crucial aspect of the modernist reaction against the Victorian era. It examines Woolf’s deep engagement in her fiction with life-writing forms, from the bildungsroman of The Voyage Out to the play with conventional biographical forms of Jacob’s Room, Orlando, The Waves, and Flush and the autobiographical foundations of To the Lighthouse. It also examines her biography of Roger Fry, and her own experiment in memoir-writing, the posthumously published ‘A Sketch of the Past’, in the context of concerns with the nature of memory, identity, and sexuality.
