The sculptor Takis (1925-2019) whose real name is Panayótis Vassilákis, is a major figure in kinetic art. Fascinated by movement, it was in France, in 1953, that he discovered metal work. Self-taught, the Greek artist quickly established himself on the contemporary scene with his mechanical works. Among them, his emblematic "Signals", long iron rods associated with luminous and electromagnetic elements, echo the industrial and railway landscapes. In the 1960s, the artist became close to the Fluxus group and designed several musical sculptures. A fervent defender of art accessible to all, he also created works in public spaces, such as in La Défense, and opened the Research Centre for Art and Science near Athens.
