... of brown coloration in the presence of chromate salts was reported by Bertholdus Werner in 1857 ( 1 ). Alfred Kohn coined the terms “chromaffin reaction” for the color change and “chromaffin cells” for the reactive cells. He went on to map the chromaffin tissues in other parts of the body, and conceived...
