Seymour Meyerson was born and raised in Chicago, Illinois and attended the University of Chicago from which he received his undergraduate degree. By 1943 Meyerson began active service with the US military, spending the majority of his time with the Signal Corps; he also performed important work as the technical liaison officer between the Manhattan District and Standard Oil Company (Indiana). His time with the military afforded him the opportunity to be trained in electronics and to encounter his first mass spectrometer. In 1946 Meyerson started what would become a nearly forty year career with Standard Oil Company (Indiana) (later the Amoco Corporation). From the outset, Meyerson was involved with the mass spectrometry group, first conducting quantitative gas analysis on gases and low-boiling liquids, consisting of hydrocarbons and fixed gases.
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.
