Hermann Niemeyer Fernández (26 October 1918 – 7 June 1991) was a well-known Chilean scientist who did much to establish biochemistry as a research discipline in Chile.

Membership of this group, illustrated at a web page[2] about Nicanor Parra that has a photograph that includes Niemeyer as a young man (easily recognizable to those who knew him as an old man), marked Niemeyer's character: his preference for frank and rigorous discussion; his humanism; his liking of music and painting; and his strictly republican politics.

In 1943 he obtained the title of Doctor of Surgery for his thesis Contribución al estudio del metabolismo de la célula hepática (Contribution to the study of metabolism in the liver cell).

He was the first to report that this enzyme, monomeric in structure, displayed sigmoidal kinetics with respect to its substrate, glucose,[6] a property previously thought to require multiple subunits.

He died in Santiago, Chile, on 7 June 1991 Source:[1] In 1952 he and Julio Meneghello were awarded the Nestlé Prize for their work on infantile malnutrition.
