A collection of former students, research associates, colleagues, and family members joined together to establish, in 2017, the Harden M. McConnell Lectureship at Caltech. The annual lectureship, named in honor of McConnell (PhD '51)—who taught at Caltech for more than a decade and is widely recognized as one of the leading physical and biophysical chemists—aims to bring to the campus outstanding scientists to present on physical chemistry research.
