Julio Le Parc obituary
Radical Argentinian artist who demanded the viewer participate in his kinetic art
“Art today is nothing but a tremendous bluff,” Julio Le Parc complained in his 1963 manifesto, presenting a series of home truths to the French cultural establishment. “The public is a million miles away from artistic events.” The Argentinian artist, who has died aged 97, had relocated to Paris and was caught up in the social revolts of the decade. His solution was a radical series of works that experimented with light, movement and colour, and required the active participation of the viewer.
The earliest of these included large-scale mobiles, each dramatically spotlit, the wire-hung metal and plastic fragments moving as the viewer walks around the sculptures, light bouncing between the shiny elements. For Le Parc these works were not about spectacle, but shaking the viewer from apolitical lethargy, a disease he thought permeated the museums and galleries of the day. It was, he wrote, a “wish to lead viewers out of their apathetic dependency that makes them passively accept not just what is forced on them as art, but an entire way of life”.
From these initial experiments, Le Parc went on to make even more ambitious, experiential works, including labyrinths, sensory installations and interactive games, each a “quasi-coproduction” with the spectator, as he put it.
His Lumières Alternées (1963-93) featured moving lights that the viewer has to negotiate; in a 1978 work from the series, included in a retrospective dedicated to Le Parc currently at Tate Modern, viewers are encouraged to walk through a disorientating maze of laser-lit hanging transparent curtains. In Ensemble of Eleven Surprise Movements (1965) and Pattern to Manipulate (1967), the viewer activates a series of noisy, mechanised elements, from spinning wheels to rattles, by pressing buttons. Le Parc’s manifesto commanded: “It is prohibited not to participate. It is prohibited not to touch. It is prohibited not to break.”
Born not far from the Andes in Palmira, a suburb of the western city of Mendoza, Julio was the son of Angelina Andino, a seamstress, and Juan Le Parc, a Frenchman who worked on the railways. Julio went to the local elementary school until the age of 13, when he left to take various jobs to bring an extra income into the family, including repairing bicycles and at a factory making fruit crates.
His parents separated when he was 15, and he, his mother and brothers moved to Buenos Aires. There Julio resumed his education with evening classes at the Escuela de Bellas Artes Manuel Belgrano while working by day at a handbag factory. The family’s straitened circumstances engendered the leftwing politics that informed his entire career.
He was also able to take a weekly sculpture course taught by Lucio Fontana until 1947 when, aged 19, he abandoned both his studies and family in “a total and confused rebellion against submission and obedience”, taking off around Argentina and moving in various anarchist and Marxist circles.
His eventual return to art school in 1954 coincided with the worsening political situation in Argentina. Nonetheless, that year he married Martha Boto, a textile artist who was also studying at the Escuela Superior de Bellas Artes Ernesto de la Cárcova. After the 1955 coup that deposed President Juan Perón, the couple started searching for ways to escape, with Le Parc landing a travel grant from the French government.
They arrived in Paris in 1958, and he began work on what he described as a series of “systematic” black and white abstract paintings, collectively titled Surfaces, in which the patterns he made appeared to move as an optical illusion.
Two years later he founded Grav (Groupe de Recherche d’Art Visuel), six French and Argentine artists who shared his dislike of art’s “mystification” and distrust of its bourgeois and capitalist sensibilities. They participated in the 1963 Paris Biennale with Labyrinth, a compendium of 20 “environmental experiences” including op art wall reliefs and kinetic light installations, then Documenta in Kassel, Germany, in 1964, and the Venice Biennale in 1966, where he won the painting prize. In the same year Le Parc had his first solo show, at Howard Wise Gallery in New York.
Grav’s most radical work, however, happened outside. On 19 April 1966, from 8am to midnight, they organised A Day in the Street, which involved the artists planting balloons in Paris’s fountains and a giant kaleidoscope in the Jardin des Tuileries, with those passing by the Opéra Metro offered the chance to wear kinetic sculptures. The day ended with a light show along the Seine.
While Grav’s activities were deemed not radical enough by Situationist International (the Marxist activists influential in the May 1968 protests believed the collective was merely turning the “passive spectator” into a “stimulated spectator”), Le Parc did not hold a grudge. During the 1968 protests he was instrumental in the Atelier Populaire, producing posters for the student movement. For this he was briefly expelled from France, travelling around the rest of Europe for several months.
While Le Parc had taken part in the 1967 SĂŁo Paulo Biennial, he joined the 1969 boycott against the show when Brazil’s military regime entered its most censorial phase. In 1970 he travelled to Cuba to learn about the revolution, then on to Puerto Rico for the first Biennial of Latin American Print, and Colombia for the MedellĂn Biennial. That year his work was shown in London for the first time, in Kinetics, a group exhibition at the Hayward Gallery, dedicated to mechanical art. In 1972 Le Parc was offered a retrospective at the MusĂ©e d’Art Moderne in Paris. “Driven by my anti-institutional convictions, I decided to leave it to chance with heads or tails. I asked one of my children to toss a coin; it came out tails.” Consequently, he turned the show down.
Museum surveys did come, however, at the Museo de Arte Moderno, Mexico City, in 1975, and FundaciĂł Joan MirĂł, Barcelona, in 1978. That year he was also the subject of a BBC documentary. By now Le Parc was making several solo exhibitions a year, but his activism continued unabated. He joined the International Brigade of Anti-Fascist Painters and founded Espace Latino-Americain, an atelier promoting art from the region and coordinating campaigns against South American rightwing military regimes. In 1986, he participated again in the Venice Biennale, as well as the Havana Biennial, in which he led workshops for young Cuban artists.
In the 90s his popularity dipped, but by the turn of the century he was given a homecoming touring retrospective in Argentina, with another US tour between 2010 and 2011. In 2013, the Palais de Tokyo staged his first major retrospective in Paris. Attracting 220,000 visitors, it marked the most successful show in the institution’s history. A year later, the Serpentine Galleries in London held his first solo exhibition in the UK.
He and Marta separated but remained close until her death last year. He is survived by his sons, Juan, Gabriel and Yamil, and five grandchildren.
