Pierre Vasarely is the grandson of Victor Vasarely, founder and leading light of Op Art. They say Pierre has inherited his grandfather's benevolence and engaging humour. Even so, he has had to battle through a whole legal saga to save the soul of his grandfather's oeuvre. Victor Vasarely's work, though rooted in art history, remains totally modern; it opened the way to many contemporary forms such as digital, kinetic and architectonic art. At the emblematic Vasarely building on its hilltop at Jas-de-Bouffan in Aix, Pierre is constantly developing the resonances of his grandfather's work. 2016 marks the 110th anniversary of the artist's birth and 40 years of his Fondation. The museums of Budapest and Pecs in Hungary, Gordes municipal council and the Fondation Vouland in Avignon have pitched in to help organise a three-part exhibition called MultipliCité (until 2 October). In Avignon, Victor Vasarely... en mouvement presents 150 works reflecting the artist's early career as a noted poster artist and designer. L’Alphabet plastique, at Château de Gordes in the Luberon, takes a historical and explanatory approach. L’art pour tous at the Fondation Vasarely in Aix pays tribute to his universalism. This is a wonderful triple opportunity to enjoy the legacy of an artistic adventure of which Pierre Vasarely was a privileged witness.
