Dr. Seán Patrick McGlynn, Boyd Professor of Chemistry Emeritus, Dean of Graduate School, Vice-Chancellor for Research, recipient of the von Humboldt Prize, University of Bonn, Physics Institute, Germany, and beloved father, we miss you. Seán P. McGlynn died at his home on Pecan Grove Court, Baton Rouge, La. at the age of 93 on Friday, May 3, 2024. He was the devoted father of 8 children. Dr. Seán P. McGlynn, a native of Dungloe, Ireland, was born on March 8, 1931, and earned his Bachelor of Science degree in chemistry and Master of Science degree in biochemistry from the National University of Ireland in 1951 and 1952. He earned his doctorate degree in chemistry at Florida State University in 1956 and joined the LSU faculty as an assistant professor of chemistry in 1957. He was named Boyd Professor in 1968, LSU's highest academic rank. A noted teacher and mentor, he is a prolific author (399 publications) and highly requested speaker in a broad range of fields including chemistry, physics, and radiation biology. His career reached far beyond his research and teaching into administration. He was named dean of the Graduate School for a one-year term from 1981-82. In 1981, he was also named Vice Chancellor for Research. It was in this role that McGlynn left his indelible mark on the university. Through his efforts, LSU achieved the Carnegie Foundation's Research I University ranking, placing it in the top 70 institutions in the nation. He is credited with dramatically enhancing research productivity and funding in the science, technology, engineering, and math (STEM) disciplines. His contributions also led to the acquisition of $25 million in federal funding for the synchrotron facility (CAMD), the restructuring of the LSU museum complex, creation of the Center for Energy Studies, development of the proposal for the endowed chairs as part of the 8g trust fund, and to the creation of the Boyd Professor Research Fund. He co-authored the eight documents entitled "Quality Thrust Initiative" which ultimately saw the creation of research clusters across the campus in areas such as biotechnology, coastal and environmental sciences, physical sciences, and computer and information sciences. He retired in 1998, and continued his research, writing, and teaching within the Department of Chemistry at LSU.
