  • Title: [Final clarification of Goethe's findings in the examination of color blind patients].
    Author: Jaeger W.
    Journal: Klin Monbl Augenheilkd; 1989 Dec; 195(6):382-7. PubMed ID: 2695690.
    Abstract:
    During his researches on colour-vision Goethe has examined two colour blind students. The reports and the colour tests made by Goethe himself are mostly preserved. Due to the colour confusions in the whole purple zone Goethe decided that the subjects were blue blind. During the 19th century-- however--the supposition arose that it must have been a red-green-blindness. It was Trendelenburg, who supposed a deuteranopia. On the other hand reconstructions of Goethe's examinations had the result that it was in all probability a protanopia. A final solution of this discussion is now possible after a great-grandson of Goethe's subject Gildemeister was found out and examined at Nagel's anomaloscope. He is a typical protanope. According to the pedigree demonstrating the typical x-linked hereditary transmission, we can be sure that Goethe's subjects were protanopes.
