  • In Memoriam: Dr. John C. Herr

    Dr John Herr
  • The Department of Cell Biology mourns the death of Professor John Herr, a member of the department since 1981. John was a well-regarded colleague, teacher, mentor, researcher and entrepreneur who brought a high level of enthusiasm to everything he did. He was, at heart, a reproductive biologist with a career long quest to translate his basic research on the male and female reproductive systems into new forms of contraception as well as new diagnostic tools. He founded a number of local biotech companies and he brought SpermCheck, a novel sperm diagnostic based on his early research to worldwide markets. In recent years, his reproductive immunology research led him to pursue a novel approach to cancer treatment. John had many close colleagues and collaborators throughout the School of Medicine and he easily bridged the gap between the basic and clinical and commercial realms. He had a passion for teaching his colleagues and students about the methodology of translational research and pioneered a graduate course in this area, which recently received NIH funding. John had many international ties and for much of his career reached out to India to train reproductive researchers. He is missed.
