Lectures, Addresses, and Publications includes papers for Copenhagen (1958-1965) and Cambridge (1968-1975), and occasional brief correspondence accompanying the lectures. The subjects chosen reflect Weis-Fogh's main research interests at the given time, but talks on insect flight recur throughout the period covered. Much of the material in the first part is in typescript and was designed for distribution to students rather than as a basis for lectures delivered by Weis-Fogh. He continued to give talks in Denmark after his move to Cambridge in 1966, and much of the material is in Danish. There is some overlap with section F.
