John Michael Hayes (6 September 1940 – 3 February 2017)ForMemRS was a scientist emeritus at Woods Hole Oceanographic Institution in Woods Hole, Massachusetts.
Hayes was educated at Iowa State University graduating with a Bachelor of Science degree in Chemistry in 1962. He completed his postgraduate education in analytical chemistry at the Massachusetts Institute of Technology (MIT) where he was awarded a PhD in 1966 for analysis of organic constituents of terrestrial and extraterrestrial samples using mass spectrometry supervised by Klaus Biemann.
Hayes made the first measurements of the distribution of the isotopes of carbon within biolipids. This innovation provided a foundation for new studies of the pathways of carbon in natural environments, both modern and ancient.
Because the production of organic matter requires concomitant production of O₂ or some other oxidized product, Hayes’s studies of the carbon cycle bear strongly on the development of the global environment and provide evidence about the timing of evolutionary events such as the development of O₂-producing photosynthesis.
For 26 years he was Professor in the departments of chemistry and geology at Indiana University Bloomington, then moved to Woods Hole Oceanographic Institution. During his career he has held academic appointments at Harvard University, the University of California, Los Angeles and the University of California, Berkeley.
