Seymour Herbert Hutner was a microbiologist specializing in the nutritional biochemistry of protist

Protists are a diverse group of eukaryotic microorganisms. Historically, protists were treated as the kingdom Protista, which includes mostly unicellular organisms that do not fit into the other kingdoms, but this group is contested in modern taxonomy...

, or cyanocobalamin. He developed a nutritional assay method for vitamin B12 using Euglena that was used for many years in hospitals to test for B12 levels in blood, eventually being replaced by other methods

After graduating from Cornell, he joined an independent research laboratory, the Haskins Laboratories

 founded by the physicist Franklin Cooper and the entomologist and geneticist Caryl Haskins. Initially this was based in Massachusetts, near M.I.T., but then it moved to a building on East 43rd Street in New York City, where Hutner was joined by a newly arrived Italian scientist, Luigi Provasoli, who had spent time in the laboratory of Andre Lwoff in Paris. In New York, during the 1940s through the 1960s, Haskins Labs became known for studies of protistan nutrition and the development of culture media and culture assay methods. Hutner was one of the first to appreciate the importance of organic complexing agents in trace metal nutrition of cells . This had significant implications for the development of culture media and also in the understanding of microbial ecology. With his colleague Luigi Provasoli he showed that photosynthetic organisms could be ‘bleached’ by the antibiotic streptomycin

 in Lower Manhattan, where he became a professor. At Yale, Cooper developed an institute for the study of speech and linguistics which remains today under the name of Haskins Laboratory. In New York, Hutner's component, focussed on microbiological research, has become a department of Pace University and is named Haskins Laboratories, but the two similarly named laboratories no longer have formal ties. At Pace the lab became a center for metabolic studies of protistan parasites, as well as studies of behavioral ecology and sensory physiology of free-living protists. Under the leadership of Hutner's student, Cyrus Bacchi, the former led to development of the antiparasitic drug eflornithine

 (alpha-difluoromethylornithine), widely used today against African sleeping sickness (trypanosomiasis). Work on antiparasitic drugs continues today under the direction of Nigel Yarlett.

Hutner was a founding member of the Society of Protozoologists (now the International Society of Protistologists) serving as its president in 1961-2, and was for many years on the editorial board of the Journal of Protozoology (now the Journal of Eukaryotic Microbiology). In 1977 an issue of the journal was dedicated to him.Levandowsky, M. (Ed.) 1977. A collection of papers dedicated to Seymour H. Hutner. J.
