Doherty, M. Julesz, B., 1971. Impossible Triangle - The Illusions Index. The Impossible Triangle (also known as the Penrose Triangle or the Impossible Tribar) was first created by Oscar Reutersvärd (1915 - 2002), a Swedish graphic artist known as the ‘father of the impossible figure’.
It is anecdotally, but widely reported that he created it in 1934, aged 18 while doodling as a student in his Latin class. The illusion was independently discovered later and popularised by Lionel Sharples Penrose (1898 -1972), a British psychiatrist, geneticist, and mathematician, and his son Sir Roger Penrose (1931 -), a British mathematician, physicist and philosopher of science. Penrose and Penrose published the illusion in the British Journal of Psychology in 1958. The Penrose Triangle is an impossible figure (or impossible object or undecidable figure): it depicts an object which could not possibly exist. It is impossible for the Impossible Triangle to exist because in order for it to exist rules of Euclidean geometry would have to be violated. Optical Illusions And Pictures.
