In 1960, in her studio at Lintgasse 28 in Cologne, she launched a series of gatherings of members of the evolving global artistic movement Fluxus. At her invitation, avant-garde poets, composers and visual artists such as Hans G. Helms, David Tudor, John Cage, Christo, Wolf Vostell, George Brecht, and Nam June Paik organised unconventional concerts of the "newest music", readings, exhibits, and actions. These activities have been described as "comparatively non-hierarchical exchanges of information across national, disciplinary and age boundaries", contributing in that way to the character of the Fluxus movement which had been developing during the 1950s.
