Abstract
The article retraces the social and institutional circumstances that in 1986 led two researchers at the IBM laboratory near Zurich, Müller and Bednorz, to discover high-temperature superconductivity. After confirmation of the unexpected breakthrough an unprecedented mobilization of research groups all over the world took place while simul taneously high-temperature superconductivity (HTS) turned into a subject of intense media interest. The authors discuss these events under three perspectives: the closer interlinkage capacity of researchers and the relationship between the social organization of research and unforeseen cases of scientific creativity.
