saw this and started to use saltwater-filled balls themselves. The "Cologne Discipline" was demonstrated as a competition sport at the national games in 1963, probably the first official game with an underwater ball. At the time, though, there was not much interest shown. Dr. Franz Josef Grimmeisen, a member of the German Underwater Club in Duisburg, a city near Cologne, decided to make a competitive sport from this ball game. The German Lifeguard Association (DLRG) of Mülheim (since 1967 TSC Mülheim/Ruhr) had founded a divers' club, and through contact with members of DUC Duisburg learned of the game. With their help, Grimmeisen arranged the first underwater rugby game on Sunday October 4, 1964. It took place between DLRG Mülheim and DUC Duisburg. DUC Duisburg won the game 5–2. The next edition of the Essener Tageblatt carried the story. Grimmeisen kept promoting the ideas of an underwater rugby tournament to give the sport a character of serious competition. Together with the scuba-diving section of the DUC Mülheim/Ruhr, to which six players of DUC Duisburg came, he organized the first underwater rugby tournament rules, and the "Battle for the Golden Ball" in Hallenbad Sued, in Mülheim/Ruhr. The premiere was on November 5, 1965. Six clubs sent teams to Mülheim: DUC Bochum; DUC Düsseldorf, DUC Duisburg, DUC Essen and TSC Delphin Lüdenscheid. The rules of those days allowed 8-player teams, and DLRG Mülheim, the home team, came away winners, against DUC Duisburg (for whom Dr. Grimmeisen played). The tournament has been held every year since then, which makes it the oldest tournament in the history of the sport. The Cologne version of the game was only played for a short time thereafter in Cologne, and has been long since forgotten. The Cologne team itself also turned to underwater rugby. To bring this game to the international arena, Grimmeisen turned to the two then most important members of CMAS, France and the USSR. He offered demonstration games and press coverage. Interest was not forthcoming. Just one French sport magazine, L'Equipe, printed a short article in its April 9, 1965 edition. The Scandinavian countries showed more interest, and adopted the ideas in relatively short time. A demonstration in Denmark in 1973 and in Finland in 1975 were effective. Games in Belgium in September 1973 and Vienna in 1979 were ineffective in generating interest. In the Eastern Bloc, only Czech teams were interested, and they, according
