Artist and teacher, born and died in London. Derham was a prolific painter of large, colourful and vibrant pictures, such as circus scenes, figurative but tending towards abstraction. She studied at Slade School of Fine Art, 1961–6, gained her diploma with distinction in painting in 1965, then a postgraduate diploma in 1966. Her teacher Frank Auerbach remembered her as a “rather beautiful and brilliant” student, and Michael Andrews and Bert Irvin also admired her work. Derham won the Walter Neurath Prize for Drawing and Painting, 1962; an Italian Government Scholarship for study in Italy and an Ian Stevenson Travelling Scholarship, both 1965; Boise Travelling Scholarship, 1966; and an Arts Council Grant, 1972. She taught part-time at Byam Shaw School of Art and occasionally at the Slade.
