Johannes von Kries
From Wikipedia, the free encyclopedia
Johannes von Kries (1853–1928) was a German physiological psychologist[1] who formulated the modern "duplicity" or "duplexity" theory of vision mediated by rod cells at low light levels and three types of cone cells at higher light levels.[2][3]
When von Kries was at Freiburg, he was called to succeed Professor Du Bois Raymond as chair of physiology at the University of Berlin, but he declined.[4]
Von Kries has been called Helmholtz's "greatest German disciple".[5]
