Catherine Fenselau grew up in York, Nebraska. Always interested in science, first archaeology and ultimately chemistry, she attended Bryn Mawr College. The chairman of the chemistry department, Ernst Berliner, became the first of her three mentors. Fenselau received her PhD in organic chemistry from Stanford University, working in the lab of Carl Djerassi, who became her second mentor. For her postdoc at Berkeley, she entered Calvin Melvin's lab, working directly with Alma Burlingame, then at Johns Hopkins University she worked on a broad range of biomedical problems, and her research shifted its direction more toward biochemistry. Her third mentor, Paul Talalay, helped her buy her first spectrometer, which she used for bacterial analysis and for research into anti-cancer treatments. Fenselau accepted the chairmanship of the chemistry department at University of Maryland, Baltimore County, where she established a regional mass spectrometry center. She began analyzing whole proteins, publishing papers about using mass spectrometry to map protein topography and about HIV Gag proteins. Fenselau moved to University of Maryland, College Park, for a two-year stint as chairman of the chemistry department. She was involved in the study of anthrax-Amerithrax-promoting the rapid detection and characterization of bacteria with mass spectrometry and she established the US Human Proteomics Organization (USHUPO), becoming its first president. She continues to teach and to conduct research in proteomics and bioinformatics.
Michael A. Grayson is a member of the Mass Spectrometry Research Resource at Washington University in St. Louis. He received his BS degree in physics from St. Louis University in 1963 and his MS in physics from the University of Missouri at Rolla in 1965. He is the author of over 45 papers in the scientific literature. Before joining the Research Resource, he was a staff scientist at McDonnell Douglas Research Laboratory. While completing his undergraduate and graduate education, he worked at Monsanto Company in St. Louis, where he learned the art and science of mass spectrometry. Grayson is a member of the American Society for Mass Spectrometry (ASMS), and has served many different positions within that organization. He has served on the Board of Trustees of CHF and is currently a member of CHF's Heritage Council. He currently pursues his interest in the history of mass spectrometry by recording oral histories, assisting in the collection of papers, and researching the early history of the field.
