Abstract: | It is an honour to be asked to speak at this, the Silver Jubilee of the International Symposia in 1984, in the presence of a number who, unlike myself, were present at the first symposium at the General Motors Research Laboratories in 1959 - Gordon Newell, Martin Beckmann and, foremost of all, Robert Herman, whose work is to be recognized next week by the award of an Honorary Degree at the University of Karlsruhe. Because it is such an honour to be asked, I had no hesitation in accepting Professor Volmuller's invitation, several months ago - to address you with a causerie on a subject of my choice. |
