Abstract
IN NATURE of September 23 reference is made to the death of Dr. A. F. Holmgren, professor of physiology in Upsala University: “His attention,” it is said, “was in the early seventies directed to colour-blindness, and in 1878, he published his well-known work on colour-blindness in relation to railways and the Navy, thus bringing to a practical issue the work long before begun by George Wilson, of Edinburgh (1855). This led him to the invention of his now well-known worsted test for colour vision.”
