Former Lehigh Provost and Vice President for Academic Affairs Arthur Earl Humphrey, distinguished chemical engineer, biotechnology pioneer and internationally renowned scholar, passed away on March 21, 2026. He was 98.
Born in Moscow, Idaho, Humphrey earned bachelor’s and master’s degrees in chemical engineering from the University of Idaho. In 1953, he earned a Ph.D. in chemical engineering with a focus on biochemical engineering from Columbia University. He later earned a master’s degree in food technology at the Massachusetts Institute of Technology.
He began his notable academic career at the University of Pennsylvania, where he taught biochemical engineering. During his tenure, he served as Chair of the Chemical Engineering department for 10 years and later as the inaugural Dean of Engineering and Applied Science for eight years.
In 1980, he joined Lehigh University as provost and vice president for academic affairs, where his purposeful leadership worked to expand research support and advocate for interdisciplinary education, principles that remain central to Lehigh’s mission today. Believing strongly in experiential learning, he helped position the university for continued academic growth and opportunity.
“Arthur was a presence on campus during my time as a student at Lehigh,” said President Joseph J. Helble ‘82. “Even as a young chemical engineering student I knew of his work, and knew that he was a pioneering chemical engineer. Arthur’s impact on biochemical engineering cannot be overstated, and his leadership, as many others have shared, made such a positive difference for the Lehigh community.”
During his time at Lehigh, Humphrey also chaired Lehigh’s Biotechnology Institute and was named the Diamond Professor of Biochemical Engineering in 1986. In recognition of his achievements and contributions to both the university and the field, Lehigh awarded Humphrey an honorary doctorate in 1993.
“It is well known that Arthur was an accomplished administrator and an exceptional scientist. But what most people remember about Arthur was his humanity,” said Mohamed El-Aasser, professor emeritus of chemical engineering and former provost.
“Shortly after his arrival on campus in 1980 as Lehigh’s new provost, Arthur came to my office to meet me in person and learn more about our plans for space shuttle experiments, and to review the timeline for my promotion to full professor. With all his new responsibilities as the provost, his humanity is what brought him to my office that day and cemented our lifelong personal friendship and extended to our two-family friendships.
“He was an excellent role model for how to balance administrative duties and the advancement of his own vigorous research program in bioengineering, which involved mentoring students and providing leadership for research. This was a lifelong skill that he maintained even after his retirement from Lehigh in 1992, continuing to do research that he loved most.”
After retiring from Lehigh, Humphrey continued his academic service at Penn State University, where he chaired the Biotechnology Institute and taught biochemical engineering, extending his influence to a new generation of engineers and scholars.
Throughout his career, he remained deeply committed to advancing engineering research, education and public impact across institutions and disciplines. His emphasis on interdisciplinary collaboration and experiential learning continues to shape Lehigh’s approach to engineering education today.
The Arthur Humphrey Distinguished Lecture remains an annual cornerstone of the Department of Chemical and Biomolecular Engineering in Lehigh’s P.C. Rossin College of Engineering and Applied Science, bringing leading voices in chemical engineering and biotechnology to campus each year.
"When I was the chair of the Department of Chemical and Biomolecular Engineering, we established the annual Arthur Humphrey Distinguished Lecture Series in Biomolecular Engineering in 2016,” said Mayuresh Kothare, the R.L. McCann Professor of Chemical and Biomolecular Engineering and associate dean for research in the P.C. Rossin College of Engineering and Applied Science. “Over the past decade, this series has allowed us to host seminars by leading researchers working at the interface of engineering and biomedical/biological systems.”
“Dr. Humphrey was instrumental in co-authoring a major report in 1988 by the National Research Council entitled ‘Frontiers in Chemical Engineering: Research Needs and Opportunities,’ which defined major steps in incorporating biomolecular and biological concepts in chemical engineering. This report, commonly referred to as the ‘Amundson Report,’ had a substantial impact on the subsequent evolution of the chemical engineering profession."
Over the course of his career, Humphrey co-authored three influential books, published more than 250 technical papers and advised 27 Ph.D. students, leaving a lasting legacy.
“Arthur studied how living things flourish under the right conditions and created those conditions for people at the same time,” said Stephen S. Tang M’85 Ph.D.’88 P’22, a member of Lehigh’s board of trustees and one of Humphrey’s last Ph.D. students.
Humphrey was elected to the National Academy of Engineering in 1973 for his contributions to biochemical engineering as a researcher, author and educator.
Humphrey served as president of the American Institute of Chemical Engineers (AIChE) from 1990 to 1991 and was appointed by President Richard Nixon as chair of the Industrial Microbiology Joint Committee to the USSR. He also served as a Fulbright lecturer and National Science Foundation fellow at institutions in Japan, Australia and the United States, delivering biotechnology lectures in more than 30 countries.
Among his many honors, Humphrey received the John Fritz Gold Medal in 1997 as the outstanding engineer from the Associated Engineering Societies, the University of Pennsylvania Gold Medal in 1988 for distinguished service to society and the Asian Biotechnology Gold Medal in 1991. During AIChE’s centennial, he was recognized as one of the 100 most distinguished chemical engineers of the modern era. He also received honorary doctorates from the University of Idaho and the University of Pennsylvania.
Together, these honors reflected the global reach of his scholarship and the lasting influence of his work on the field of biochemical engineering. Humphrey is remembered as a scholar, leader and teacher whose curiosity and generosity shaped generations of engineers and students around the world.
Beyond his professional accomplishments, Humphrey was an avid outdoorsman who enjoyed hiking, camping, canoeing and cycling. He was also an amateur astronomer and a fan of square dancing.
He was a resident of Scarborough, Maine and was predeceased by his three younger brothers and his wife of 74 years, Sheila Claire Darwin Humphrey. He is survived by two daughters and their husbands, and one grandson and his wife.
