H. R. Cox

Herald Rea Cox (1907 -1986), was an American bacteriologist. Born in Terre Haute, Indiana, he graduated from Indiana State Normal School, now Indiana State University, in 1928 before obtaining his doctorate from the Johns Hopkins Bloomberg School of Public Health.

In the 1930's he joined the U.S. Public Health Service as Principal Bacteriologist at the Rocky Mountain Laboratory in Hamilton, Montana. While there, he studied rickettsia, a group of organisms that causes Rocky Mountain spotted fever and typhus. In 1938, he discovered that rickettsia could be grown in fertile egg membranes, which led to the development of vaccines to combat Rocky Mountain spotted fever and vaccines for several strains of typhus.

The family Coxiellaceae and the genus Coxiella, which contain the organism that causes Q fever, are named for him.

In 1942, he became head of the Virus and Rickettsial Research Department at Lederle Laboratories in New York. At that time, public health attention focused on finding a vaccine for polio. Cox was one of many researchers competing to find a breakthrough, which is generally credited to Jonas Salk (1952). Although Cox's egg technique was in widespread use by 1943, it had not been successful for polio. In 1947, John Franklin Enders and others demonstrated that monkey tissue provided a suitable medium to grow the virus in the lab. Salk employed the Enders method, incubating the virus using rhesus monkey kidneys and testicles. Cox eschewed the technique because of the danger monkey virus represented. In October, 1952, Cox reported that he had grown the Lansing strain of polio virus in fertile hens' eggs and in 1961, he announced an oral polio vaccine. Meanwhile human trials of Albert Sabin's successful oral vaccine had began in 1957 and it would be licensed for general use in 1962.

Even within Lederle, there was competition to find a vaccine. Cox and his co-worker, Dr. Hilary Koprowski, had each developed different polio vaccines, which they vigorously defended and debated against one another. Koprowski's vaccine was finally tested but the outcome was a failure. After the attenuated live virus entered the body, it sometimes reverted to a virulent state. Nevertheless, from 1957 to 1960, large scale tests were carried out in the Congo. The results have been controversial.

Dr. Cox retired from Lederle in 1972. He was later director of cancer research at Roswell Park Memorial Institute, where he concentrated on cancer immunology.
