When Ron Unnerstall was designing the course he will teach this spring as the Brenton S. Halsey Distinguished Visiting Professor in Chemical Engineering at UVA, he had a straightforward goal: Give his students a jumpstart on the insights gleaned during his 34-year career in the petroleum industry. “I led global organizations, worked in different countries and dealt with very serious risk management issues,†Unnerstall said. “The lessons I learned along the way need to be passed on.†That is the critical value of the Halsey Professorship: allowing the next generation to benefit from hard-won wisdom. The James River Corporation endowed the position more than two decades ago in honor of one of its founders. It was established to bring to Grounds industry leaders in chemical engineering and related fields whose broad practical experience can influence the education, scholarship and professional development of undergraduates in the School of Engineering and Applied Science.
