In J. Opl Res. Soc. 40, 115-136, (1989), transcripts were given of four talks by some of the first OR workers describing their experiences during World War II. The present paper supplements these by recording notes, made by the speakers themselves, on two further talks on early OR which were given 'after-dinner' at the 1989 and 1990 International Symposia on Military Operational Research which is arranged annually at the Royal Military College of Science, Shrivenham, UK by Professor R. W. Shephard. By way of introduction to each talk, Professor Shephard has given a brief account of the speakers' careers and the chronology of the organizations of which they formed a part.
