Masters of All Trades: Polymathy’s Past, Principles, and Promise explores how cross-disciplinary insight can helpaddress the defining challenges of our time—from pandemics and climate change to AI ethics—while extracting practical lessons and strategies for innovation, problem solving, and interdisciplinary professional work.

Drawing on civilizations from China to medieval Persia, pre-modern Europe, and India, and informed by research in history, cultural studies, neuroscience, and creativity, the book investigates why polymathic creativity thrived in some eras, declined in others, and how it might be revived today. Through vivid biographies of history’s most versatile thinkers, including Hypatia, Aryabhata, Omar Khayyam, Leonardo da Vinci, Leibniz, and Thomas Young, it uncovers patterns behind expansive creativity and integrative thinking. Lesser-known women and non-Western polymaths are also highlighted, offering a global and inclusive perspective. Adopting a meta-polymathic approach, the book applies polymathic thinking to the study of polymathy itself. It situates polymaths within their cultural, historical, and institutional contexts and explores biological, neuroscientific, and behavioral factors that nurture such versatility. Looking to the future, it introduces the “neomath,” an AI-augmented polymath, and examines the possibilities for human–AI collaboration across disciplinary boundaries.

By uncovering the principles of polymathic creativity and advocating its revival, Masters of All Trades inspires readers to rethink mastery across disciplines. It will resonate with intellectually curious readers, researchers, educators, and professionals eager to explore the intersections of history, science, technology, and creativity, while gaining a framework for addressing complex real-world problems.

Deepak Doraiswamy holds a doctorate in Chemical Engineering from the University of Delaware and has published and lectured internationally on scientific subjects, including a definitive chapter on rheology in the CRC Handbook of Engineering. Over a three-decade career, he held senior research positions at DuPont and GE Aviation and served as Chief Scientist at SABIC. He was also an Adjunct Professor at the University of Delaware and West Virginia University and worked as an independent consultant. His technical contributions span advanced materials, polymer science, and rheology, including two “named equations” and a highly cited article on the history of rheology. In recent years, he has pursued independent interdisciplinary studies of polymathy across cultures and historical periods, drawing on insights from the humanities, neuroscience, and studies of creativity. His work explores how exceptional individuals integrate knowledge across domains and what the future may hold for polymathy.
