Death brought to a close the brilliant scientific career of Dr. Marion Dorset, at his home in Washington, D.C., July 14, 1935, after an illness of a few days. Coronary thrombosis was the cause of death. Dr. Dorset had been actively at work until a few days before his demise.
Although he had many scientific achievements to his credit, undoubtedly Dr. Dorset was best known through his work in the development of anti-hog cholera serum, over a quarter of a century ago.
Born in Columbia, Tenn., in 1872, Dr. Dorset attended the University of Tennessee and was graduated in 1893, with the degree of Bachelor of Science. He then studied medicine for a year, at the University of Pennsylvania. He entered the service of the U.S. Department of Agriculture in 1894, as assistant chemist, and was assigned to the Biochemic Laboratory under the late Dr. E.A. de Schweinitz.
While thus employed in Washington, he continued his medical studies at George Washington University and he was able to complete the work for the degree of Doctor of Medicine in 1896. Shortly thereafter, the Biochemic Laboratory became the Biochemic Division of the Bureau of Animal Industry, with Dr. de Schweinitz as chief. Dr. Dorset was made assistant chief on January 1, 1900, and succeeded Dr. de Schweinitz as chief, on February 15, 1904, a position which he held until his death. In 1915, Dr. Dorset received the degree of Doctor of Veterinary Medicine (honoris causa) from Iowa State College.
The scientific investigations conducted by Dr. Dorset during the forty years of his connection with the Bureau of Animal Industry, covered a very broad field. Without any question, his investigations of hog cholera brought him the greatest fame. These studies established the fact that the causative organism of hog cholera is a filtrable virus. The next greatest step was the development of a method for producing an antiserum, at first an extremely crude biological product as these are judged nowadays. Toward the close of the year 1905, Dr. Dorset and his assistants demonstrated conclusively that a hog could be protected from hog cholera. In 1906, the method was patented by Dr. Dorset, all rights to its use being dedicated to the public, without the payment of any royalty. Ten years later, in 1916, a method for producing clear and sterilized anti-hog cholera serum was announced and the process patented as with the earlier process. Recent years have witnessed the introduction of improvements and refinements that now place anti-hog cholera serum on a level with other
similar products. As a matter of fact, it is today the most extensively used biological product.
With the creation of the Insecticide and Fungicide Board, December 22, 1910, Dr. Dorset was named as the representative from the U.S. Bureau of Animal Industry,
at the same time being appointed chairmen by the Secretary of Agriculture. He resigned in the fall of 1912 to devote more time to the research work of the Biochemic Division. When the Virus-Serum-Toxin Act went into effect, July 1, 1913, Dr. Dorset was placed in charge, where he remained until February 17, 1917, when the Office of Virus-Serum Control was created as a separate section of the Bureau to carry out the provisions of this law.
Dr. Dorset was particularly interested in tuberculin. He supervised the production of all of the tuberculin used by federally employed veterinarians in the nation-wide campaign to eradicate bovine tuberculosis, which has been under way since 1917. During recent years, Dr. Dorset was much interested in the preparation of a new tuberculin, and, in a paper read at the meeting of the U.S. Live Stock Sanitary Association, in Chicago, December 6-8, 1933, announced the successful production of a tuberculin from cultures of tubercle bacilli on a synthetic, protein-free liquid medium. He worked out a formula for an ink that could be used for marketing federally inspected meats, and this one pieced of work has saved the United States government millions of dollars through eliminating the necessity of using tags for the purpose. Dr. Dorset likewise proposed and outlined many investigations which his associates carried out with beneficial results to agriculture and public welfare. One of these was the rapid method of detecting pullorum disease in chickens, a discovery that has been a boon to the poultry industry.
Dr. Dorset was made an honorary member of the A.V.M.A. in 1912. He was a reporter at the Eleventh International Veterinary Congress, at London, in 1930, on "Control of Swine Fever by Immunization," and at the Twelfth Congress, at New York, in 1934 on "Hog Cholera." He was a member of numerous scientific bodies, including the American Association for the Advancement of Science. He is survived by his widow, a son and a daughter.
