Oscar Reutersvärd is widely recognized as the "father of the impossible figure". He pioneered the art of creating geometrically paradoxical objects that appear three-dimensional yet cannot exist in reality.
His breakthrough came in 1934 when he designed the "impossible triangle" (later popularized as the Penrose triangle), launching a lifelong exploration of visual perception and mathematical illusion.
Reutersvärd created over 2,500 impossible figures throughout his career, developing a sophisticated visual language that challenged conventional understandings of space. His work influenced generations of artists, mathematicians, and cognitive scientists, bridging the realms of art and science.
Though often using only simple lines and basic geometric shapes, his compositions reveal the fascinating tensions between what the mind perceives and what can physically exist.
