This paper reports on visits to 24 national operations-research societies (two in Germany) and to operations researchers in ten other countries. It considers each visit to a society specifically, plus some of the visits in countries not having societies. My purpose was to promote closer relations between the Operations Research Society of America and operations researchers of other countries. The first visits were made during July–August of 1967, in conjunction with the Operations Research Around-the-World Meetings. Canada was visited in November, Central and South America in December–January, and the remaining countries in Europe during March–April of 1968. These visits included all of the world's major operations-research societies, and some others.
