Some of my recollections relate to the Aerodynamics Division at the NPL and the ARC, so to refresh my memory of their origin I have referred to the First Report of the Advisory Committee for Aeronautics—later renamed Aeronautical Research Committee—for the year 1909–10. It states there that this Committee was appointed on 30th April 1909, that it was to deal with the scientific study of the problems of flight with a view to their practical solution, and that the NPL was to organise, at Teddington, a special department to research and experiment on problems submitted to it; and further, that the Committee had put themselves in communication with the Aeronautical Society, the Royal Aero Club and the Aerial League with a view to rendering such assistance as might be possible in their work, that arrangements had been made at the Imperial College of Science and Technology for lectures in aeronautics for advanced students, and that two research scholarships in aeronautics had been founded.
