The precursor of this movement was Naum Gabo with his Realist Manifesto, later joined by Alexander Calder — also represented in the Hortensia Herrero collection — with his mobile sculptures, and finally a whole series of artists who came together in the mid-1950s at the Galerie Denise René in Paris, among whom were Jesús Rafael Soto and Carlos Cruz-Diez. Works belonging to kinetic art are those that present a perceptible movement or that need movement from the viewer in order to be perceived. Other artists, such as Ángel Duarte and Andreu Alfaro (with his generatrices), or more recently Ann Veronica Janssens and Iván Navarro, have continued this line of work, which in some cases could also be described as op art. With these works, as Carlos Cruz-Diez said, ‘art went from being contemplative to being participatory’.
