Arthur König

"For information on the Italian luger, please see Arthur Konig (luge)."

Arthur König (1856–1901) was a student of Helmholtz who studied human color vision and color blindness. He proposed that dichromacy, the most common form of color blindness, was from the absence of one of the three "fundamental sensations" (now known as cone photopigments). By asking observers to match colors with a color-mixing device, König and Dieterici (1886) accurately inferred the spectral sensitivities of the three cone photopigments. König (1894) also demonstrated the similarity of scotopic spectral sensitivity (the sensitivity of the rod cells) to the radiometrically measured absorption spectrum of the rod photopigment, rhodopsin.
