Koos van Vlijmen (Rotterdam, 15 July 1909 - Rotterdam, 9 June 1989) was a painter, sculptor and graphic artist. Color, shape and line determine his art. His abstract work is characterized by strong distortions and deformations, which give it a great expressiveness. Recognizable are organic human forms in combination with vegetative and mineral forms. His works are rhythmically painted with intense colours. The color has a spatial effect, which is partly caused by the way in which the color surfaces are painted. Van Vlijmen was a member of R33, Liga New Images and Creation. His work is represented in, among others, the Stedelijk Museum Amsterdam and Museum Boymans van Beuningen Rotterdam.
