Jill Rosemary Lever was born in 1935 and educated in Brighton, where she subsequently trained as a Librarian. After a period of years spent working for a number of architectural practices, she moved to the Royal Institute of British Architects, where she was to spend the rest of her career. Together with John Harris and Margaret Richardson, she laboured on the celebrated series of drawings catalogues that was produced from 20 Portman Square between 1969 and 1984. These handsome volumes—generous in format and densely packed with information—were executed to the highest scholarly standards, earning Lever the Alice Davis Hitchcock Medallion for 1985. She succeeded John Harris as Curator of Drawings in 1987, and remained at the RIBA until her retirement in 1995. Thereafter she moved over to Sir John Soane’s Museum, where she catalogued the drawings of the elder and younger George Dance (2003), and Sir John Soane (forthcoming). Her rigorously empirical approach to the study of drawings, with its careful separation of purpose, aspect, technique, etc., remains the gold standard for students of architectural drawing and design history.
