Peter Sedgley

Peter Sedgley (19 March 1930 – 17 March 2025) was an English visual artist associated with Op art and Kinetic art. He co-founded SPACE, which is the oldest continuously operating art studio in London, and the Artist Information Registry (AIR) with Bridget Riley in 1968.

Background Peter Sedgley was born in London on 19 March 1930. His father was a railway engineer. He studied building and architecture at Brixton School of Building from 1943 to 1947. From 1948 to 1950 he completed national service with the Royal Army Ordnance Corps (RAOC) in Egypt. He worked as an architectural assistant from 1950 to 1958. In 1960 he set up a small design and construction firm making “prototype dwellings”.

Sedgley married Marguerite Erica Wiltshire in 1951. They had two children.

Art career Sedgley was "entirely self-taught" as an artist. He was initially influenced by Bridget Riley, Harry Thubron and Bruce Lacey. As his work progressed, he developed "a preference for circular forms."

Sedgley met Riley in 1961. Of his influence on her, she said "I did not know how to make a curve, even how to use a ruler, till I met Peter. I was still working on my kitchen table. He had to teach me geometry so that I could make the things I knew ought to be." In the mid-1960s Sedgley and Riley taught at Byam Shaw Art School, Kensington where one of his students was James Dyson. About Sedgley and Riley, Dyson said, "From them I learnt how to see and understand form, and ultimately how to draw it."

In 1966, the Canadian art dealer, Jack Pollock took some of Sedgley's pieces, together with ones by David Hockney, Richard Hamilton and Riley, to exhibit in his gallery in Canada, about which he wrote, "I realised that a show of this work in Canada could have a tremendous impression, not just on buyers, but on artists. I thought they would do very well to be able to see, absorb, really look at this inspiring new work. And they did – they learned a great deal."

On 5 March 1968, an event later described as an "action-happening", took place at the Tate Gallery. This experimentation led ultimately to Sedgley's creation of art using artificial light. His first work using electric light was a "light ballet", a moving light installation at Trinity College Dublin, and the Camden Arts Centre, London, in 1970.

His experiments led to the creation of "videorotors", painted discs programmed with patterns of light, using coloured light, filters, ultraviolet and stroboscopic light. Together with Frank Stella, he was "among the first painters to make use of fluorescent materials" in his work.

Sedgley worked in London until 1971 when he moved to West Berlin as part of the DAAD (German Academic Exchange Service) Berlin Artists Programme. Pimlico tube station opened in 1972 showcasing British design. Sedgley had been commissioned to design the tiles for this underground station. He remained in Berlin after the formal exchange ended, but had returned to London by the 1990s. He considered his work "'international' in spirit."

In Germany, Sedgley was "mostly concerned with the use of electric light and kinetic sculpture." His first permanent installation was "Night and Day" at Hermann Ehlers Platz Steglitz in 1974. He also experimented with the addition of music to his installations, for example at Donaueschingen Festival in 1974, when he employed music directed by Jörg Höller. Around this time, he also worked with composers Eberhardt Blum and Morton Subotnik.

SPACE and AIR In 1968, Sedgley and Riley were using Riley's house in Notting Hill as their studio, but their work started to become too large for the space. Riley said "Peter wanted to build a geodesic dome in the house, and he did it," however, it was "a tight squeeze". In the same year, they developed the idea of an Artists Information Registry (AIR), a "central repository of information about artists' work, which would be available for open consultation".This meant that buyers could contact artists directly, cutting out the need for agents. The need for somewhere to physically store this information led to the idea of a location that would house both AIR and artist studios.

In January 1969, inspired by studios they had seen while in New York for The Responsive Eye exhibition, SPACE (Space Provision Artistic Cultural and Educational) was established at St Katharine Dock, London, as a "scheme for artists' studios." Sedgley was secretary of the organisation and worked almost exclusively on the running of both SPACE and AIR.

The success of SPACE led Sedgley to develop a similar set-up in Berlin. The first exhibition, London Now in Berlin, featuring the artists who were using the London SPACE studios, was held at Messehalle, Berlin in 1971.

Group membership In November 1969, Sedgley became a founding member of the Systems Group which also included Richard Allen, Peter Loew, Jean Spencer and Gillian Wise. They "developed canvases and constructions organised in arrangements free from painterly 'accident', subjective sensation or emotion, exhibiting regular constants and variables."

Together with Bruce Lacey, John Latham and others, he created a group called "Whscht" (how one might spell the sound of a whistle) which staged "happenings" that were designed to provoke a response from the person in the street. He gave an example: "If newspapers were blowing around Tottenham Court Road, we'd come along and glue them down. The point was to provoke, to see how the public responded."
