The University of Pittsburgh community and the wider world of science mourn the passing of Professor David H. Waldeck, a distinguished and highly respected member of the university’s Department of Chemistry. Professor Waldeck, whose pioneering work shaped modern physical chemistry and nanoscience, passed away in Pittsburgh at the age of 69. His death marks the loss of one of the most influential chemists of his generation.
Born in Cincinnati, Ohio, Waldeck pursued his passion for science from an early age, earning his Ph.D. in Chemistry from the University of Chicago in 1983. After completing a prestigious IBM Postdoctoral Fellowship at the University of California, Berkeley, he joined the faculty at the University of Pittsburgh in 1985 as an assistant professor, beginning a remarkable academic journey that would span four decades.
At Pitt, Waldeck rose through the academic ranks to become a Distinguished Professor of Chemistry and served as Department Chair from 2005 to 2014. In 2015, he took on the role of Academic Director of the Gertrude E. and John M. Petersen Institute of NanoScience and Engineering, helping shape the institute into a global leader in interdisciplinary research.
Professor Waldeck was internationally lauded for his groundbreaking research, particularly his co-discovery of the chiral-induced spin selectivity (CISS) effect, a phenomenon that revealed previously unknown properties of chiral molecules and opened new frontiers in chemistry, physics, and materials science. His research combined spectroscopy, electrochemistry, and microscopy to explore electron behavior and molecular processes in the nanoscale world.
Over the course of his prolific career, Waldeck published more than 270 research papers and authored influential texts, including the widely used textbook Principles of Physical Chemistry. His work earned him numerous honors, including the American Chemical Society Award in Experimental Physical Chemistry, the Morley Medal, the Pittsburgh Award, and fellowship recognitions from the American Chemical Society, American Physical Society, and the American Association for the Advancement of Science.
Colleagues remember Waldeck as a brilliant scientist whose curiosity and dedication inspired generations of students and researchers. His leadership and vision helped strengthen the university’s research profile and fostered a collaborative community of scholars.
Outside the lab and lecture hall, he was known for his kindness, mentorship, and the genuine enthusiasm he brought to both his work and his students’ success.
