This lecture was jointly established, in 2008, in memory of James Y. Oldshue by the American Institute of Chemical Engineers (AIChE) and the Interamerican Confederation of Chemical Engineering (CIIQ/IACChE). Jim Oldshue was an important leader and supporter of the CIIQ/IACChE. He was President of the AIChE in 1979 and President of the CIIQ/IACChE in 1995. Jim was a recipient of the prestigious Víctor Márquez award in 1983, which is conferred by the CIIQ/IACChE. Jim was an ambassador of the profession who visited more than 100 countries. It is envisioned that this lecture provide a global perspective of a specific contingent topic. The Oldshue Lecture alternates between the AIChE Annual Meetings and the Interamerican Congresses, which take place every two years.
