Bridget Riley (b. 1931) is a British painter and member of the Op Art movement known for her black and white paintings that create optical effects on canvas. Born in London, she studied art at both Goldsmiths College and the Royal College of Art. Early in her career, she painted with an expressive, Impressionist aesthetic. While working as an art instructor in the early 1960s, she developed her distinctive Op Art technique, characterized by clean lines with visual effects through detailed geometry and color arrangement. She was awarded the International Prize for Painting in the 1968 Venice Biennale and an Order of the British Empire in 1974. She currently spends her time between England and France.
