*Dr. Cecil J. Watson identified cases in which there were excessive amounts of coproporphyrins in the stool and urine and suggested that this was caused by an inborn error of metabolism. He continued his research in the United States, where he and Dr. Samuel Schwartz discovered a fundamental test, the "Watson-Schwartz tests."*R. Schmid, Samuel Schwartz, and Cecil J. Watson classified the porphyries according to the porphyrin content in the bone marrow and liver.
*A. Goldberg and H. Berger showed that individuals with an excess of coproporphyrin had another inherited form of porphyria that they called hereditary coproporphyria. HCP is an autosomal dominant form of hepatic porphyria that is very similar to acute intermittent porphyria, except that some patients develop skin photosensitivity, too.
*Earnest Porphyria research in Europe and US in the 1960's.
*Heinrich Gustav Magnus described erythropoietic protoporphyria (EPP) as a genetic disorder arising from impaired activity of ferrochelatase, which is what adds iron to protoporphyrin to form heme.
*1970-2011- Drs. Anderson, Desnick, Bissell, Bloomer, Bonkovsky, Bottomley, Dailey, Galbraith, Kappas, Kreimer-Birnbaum, Kushner, Lamon, Levere, Levine, Mathews-Roth, McDonaugh, Nichols, Peters, Sinclair, Primstone, Pierach, Poh-Fitzpatrick, Sassa, Shedlofsky, Tishler, Tschudy, Watson, Phillips and many others too numerous to name have furthered porphyria research and have bettered the health care of all of the people with Porphyria.
