was held on September 1–8, 1961 in Prague, Czech Republic. It was organized by the Czechoslovak Academy of Sciences and the International Mathematical Union.
A total of 147 scientists from 18 countries, including 53 from Czechoslovakia, took part in the symposium, some of them being accompanied by their families. The largest foreign delegations were from the USA, Poland and the USSR.
An audience of more than 300 people was present at the opening ceremony which was held on September 1st, 1961 in the large lecture hall of Hotel International. The ceremony was dedicated to the memory of the late academician Eduard Čech. The main speakers were J. Kožešník, vice-president of the Czechoslovak Academy of Sciences, and the following close collaborators of E. Čech:
The Symposium took the form of presenting short scientific communications containing the results obtained in different fields of general topology and its applications. Seventy eight such communications were presented, all of which were published in General Topology and its Relations to Modern Analysis and Algebra, Proceedings of the Symposium held in Prague in September 1961 (Academia, Prague, 1962).

The list includes all papers presented at the sessions of the Symposium as well as those papers accepted by the Organizing Committee which could not for various reasons, be presented during the Symposium and were forwarded in writing only. In some cases the language and the title of the paper differ from those originally announced.
Not too many pictures were found from the 1st Toposym. The collection contains two group pictures (one can find there J. Kelley, S. Schwarz, J. Novak, R. McDowell, E. Hille, E. Michael, M. Katětov, L. Gillman, Yu. M. Smirnoff and others). There are pictures from the opening ceremony devoted to E. Čech (P. S. Alexandroff was one of the main speakers, on the other picture from the audience one can see e.g. J. Kelley). The remaining pictures are from the scientific program (the audience, V. Trnková and M. H. Stone).
