Impossible staircase, 1950s.
UNITED KINGDOM - APRIL 13: This is the first model of the 'impossible staircase' one of a series of 'impossible figures' designed by English geneticist Lionel Penrose FRS (1898-1972) in the 1950s. Penrose's discovery of the 'impossible figure' laid the foundation for the scientific study of illusions and investigations into the psychology of human perception. The Dutch artist M C Escher (1898-1972) was heavily influenced by Penrose's discovery, and incorporated an 'impossible triangle' into his well known 'Waterfall' lithograph.
