In 1964, the American Chemical Society awarded the Priestley Medal to John C. Bailar, Jr. “to recognize distinguished services to chemistry,” the Society’s most prestigious award.

He is best known for his pioneering research in the field of coordination chemistry and for his impactful role as educator. Bailar joined the staff of the University of Illinois in 1928, and, over the course of his career, became known as a highly effective educator, advising some 90 Ph.D. students during his tenure. His many research interests included homogeneous catalysis, isomerism, polymers, dyestuffs, and solid-state reactions.

Bailar published more than 200 scientific papers; almost 40 articles on chemistry education and the chemistry profession; and 11 textbooks and monographs.
