After attending school at Cheltenham Ladies College (1946-49), she studied at Goldsmiths' College from 1949 to 1952, and at the Royal College of Art from 1952 to 1955, where her fellow students included artists Peter Blake, Geoffrey Harcourt and Frank Auerbach.
In 1956, Bridget Riley attended an exhibition of American Abstract Expressionist art at the Tate Gallery, London. It was the first exhibition of its kind in the country and had a significant impact on her creative thinking. She started painting in a more exploratory style, mainly influenced by Henri Matisse and Bonard, and she started to visit more exhibitions, renewing her contact with the art world.
In the summer of 1960, she travelled and visited galleries in Italy with her teacher Maurice de Sausmarez, seeing and admiring the work of the Italian Futurist painters Boccioni and Giacomo Balla. De Sausmarez encouraged her to study the art of George-Pierre Seurat, and for a while she adopted a style of painting based on the pointillist technique. On her return, she took a part time teaching post at Hornsey College of Art. At Hornsey, Bridget Riley began her first Op Art paintings, working only in black and white and using simple geometric shapes. These patterned paintings explored the dynamism of sight and produced a disorienting effect on the eye. The following year, she moved to Croydon School of Art (1961-64) and gained her first critical recognition with a solo show at Gallery One in London (1962).
In 1965, Bridget Riley's paintings came to international notice when she exhibited alongside Victor Vasarely and others at the Museum of Modern Art in New York at an exhibition called "The Responsive Eye". One of Riley's paintings was features on the cover of the exhibition catalogue. It was around this time that the term "Op Art" entered the public consciousness. It captured the imagination of the public and became a part of the swinging sixties. The fashion, design and advertising industries fell in love with its graphic value, and Bridget Riley soon became Britain's number one art celebrity.
Bridget Riley began investigating color in 1967, the year in which she produced her first stripe painting. Her paintings of the late 1960's and 70's became mainly concerned with the visual and emotional response to color. In 1981, she visited Egypt was enchanted by the colorful hieroglyphic decoration in ancient Egyptian art, "The colors are purer and more brilliant than any I had used before", she wrote. Following her visit, she created colors in what she called her "Egyptian palette" and produced works such as the "Ka" and "Ra" series.
Bridget Riley was awarded the ACA Critics Prize in 1963 and in 1964 she was awarded a Peter Stuyvesant Foundation Travel bursary to the USA. In 1968, she won an International Painting Prize at the Venice Biennale. She has been given honorary doctorates by Oxford (1993) and Cambridge (1995). In 1998, she became one of only 65 Companions of Honor in Britain. In 2012, she became the first woman to receive the Sikkens Prize, the Dutch art prize recognizing the use of color.
“My work is ultimately inspired by nature, for me nature is not landscape, but the dynamism of visual forces - an event rather than an appearance”, Bridget Riley.
