Schrödern.

/ˈʃrəːdə/

/ˈʃrəʊdə/

Forms: Also Schroeder.

Etymology: < the name of H. G. F. Schröder (1810–85), German mathematician and physicist who first described the illusion (see Ann. der Physik u. Chem. (1858) CV. 307).

Used attributively and in the possessive to designate an optical illusion in the form of a line drawing of a staircase drawn without convergence of receding parallel lines, so that one appears successively to look down at the top and up at the underside of the staircase as the perspective reverses.
