Milein Cosman made a series of schools programmes on drawing for ITV in 1958. In all, she had nearly 30 solo exhibitions in the UK and abroad and her work has been acquired by many leading museums including the British Museum, the Victoria and Albert Museum, the National Portrait Gallery, the Ashmolean Museum, the Fitzwilliam Museum in Cambridge, the Hunterian Museum in Glasgow, the Palais des Beaux-Arts in Brussels and the Kupferstichkabinett in Berlin. She was renowned for drawing quickly, and much of her work was done from the wings or auditorium during rehearsals for concerts, theatrical and dance performances, capturing movement “in mid-flight” as Ernst Gombrich put it.
