Peter Sealy is a PhD candidate at Harvard University, where he is a Frank Knox Fellow. His dissertation charts the productive utility of photography's claim to factuality as it explored increasingly spatial qualities in late nineteenth-century architectural publications. An exposeì of this argument will appear in Blackwell's Companion to Nineteenth-Century Architecture. He co-authored (with Martin Bressani) an article on the photographs in Charles Garnier's Le Nouvel Opeìra, published in Art and the Early Photographic Album (CASVA, 2011). He holds architecture degrees from McGill University and the Harvard GSD; previously, he worked at the Canadian Centre for Architecture in Montreìal on exhibitions including Actions (2008) and Journeys (2010).
