Derek Jackson

Sir: I am writing a short memoir of Pro- fessor Derek Jackson OBE, FRS, DFC. I should be very grateful if any of your readers would be kind enough to send me reminiscences of him and his twin brother, particularly from their schooldays and when they were undergraduates at Cam- bridge.
