Last year the Royal Aeronautical Society and the Wissenschaftliche Gesellschaft für Luftfahrt agreed to organise lectures in honour of Osborne Reynolds and Ludwig PrandtI, to be given every two years, and alternating between Great Britain and Germany. The purpose of these lectures will be to show how closely English and German aeronautical research is related, and to recall the great scientific work of Osborne Reynolds and Ludwig Prandtl for the benefit of the younger generation. Without their contributions our scientific and technical achievements in aeronautics today would hardly have been possible.
Today I have the great honour to present the first Reynolds-Prandtl Lecture, and I wish to thank the Royal Aeronautical Society and the Wissenschaftliche Gesellschaft für Luftfahrt for this high distinction.
