Herman Francis Mark

Herman Francis Mark was a prominent Austrian-American chemist who made significant contributions to the field of chemistry, particularly in the development of polymer science. His work on X-ray diffraction shed important light on the molecular structure of fibers, providing crucial evidence for the macromolecular theory of polymer structure. This research helped lay the foundation for a deeper understanding of polymers and their properties.

Mark's collaboration with Roelof Houwink led to the formulation of the Mark-Houwink equation, which describes the relationship between a polymer's intrinsic viscosity and its relative molecular mass. As a long-time faculty member at the Polytechnic Institute of Brooklyn, Mark played a key role in shaping the institution's academic programs. In 1946, he founded the Journal of Polymer Science, a publication that has since become a leading platform for research in the field of polymer science. Through his work and legacy, Mark has left an indelible mark on the world of chemistry and polymer research.
