Sonia Delaunay (1885-1979), an interior and textile designer, revolutionized the use of color in the arts. Her collaboration with Robert Delaunay led to the development of Simultaneous Color, emphasizing vibrant hues. She commercialized her talent and designed geometric costumes, opened La Casa Sonia, and created popular textile patterns. During the 1930s Depression, she returned to painting and joined Abstract-Creation. Despite personal loss, she continued as a painter and designer, leaving a lasting legacy.
Influenced by the international modern art movements that had recently swept across Europe, he blended cubism, which used geometric shapes to create abstract images, and fauvism, which favoured the use of bold colours to suggest shapes, with interest in ethnography to create a unique style of portraiture that sought to reveal the subject more thoroughly than the simple rendering of physical features.
