Fred devoted most of his professional career to engineering education, research, practice, and service. He led the environmental engineering programs at the Georgia Institute of Technology (1961–1988) and then at the University of Pittsburgh (1989–2004). He was also Visiting Scholar at the University of Michigan (1967–1968) and a Guest Professor at the Delft University of Technology in the Netherlands (1976–1977). At the time of his death, Fred was Professor and Edward R. Weidlein Chair of Environmental Engineering at the University of Pittsburgh; after his death, he was awarded an Emeritus Professorship, the first time the university conferred this honor posthumously.
Fred’s research led to fundamental advances in anaerobic processes. His concept of a landfill as a bioreactor through controlled leachate recycling was adopted by the Delaware Solid Waste Authority, among many others. Fred originated and chaired the International Water Association (IWA) Specialist Groups on Anaerobic Digestion (1985–1992) and Landfill Management (1995–1999), which brought together practitioners, researchers, and educators from all over the world.
In keeping with his commitment to applying research to practice and disseminating vital information, he served as regional editor of Water Research and Water Science and Technology (both 1993–2002) and as honorary executive editor of Water Research (1994–2000). Fred could often be found on weekends in his office working on manuscripts, and thanks to his expertise, these publications became the exceptional journals they are today. From 1991 to 1998, he chaired the American Academy of Environmental Engineers (AAEE) WASTECH Program, which developed two series of books for practitioners in remediation. A writer himself, Fred was the author of more than 150 technical and scientific publications. His clear, precise, insightful prose was praised by even the most rigorous critics.
As chair of the WEF Program Committee (1989–1992), he worked to ensure that all professionals in the water-quality field were supplied with the latest science and technology. In 1989, WEF honored him with the Gordon Maskew Fair Medal for “exemplary demonstration of proficient accomplishment in the
