Gary Posner, best known for pioneering research in organocopper chemistry, joined JHU faculty in 1969
I remember Dr. Posner well for his pointed use of the Socratic method, and in particular the day that my chemistry-related sir name caught his eye. I think he always expected that I would have been born a chemistry genius because of the name Aldrich. His expectations did make my orgo studies all the more fraught and worthwhile however.
I will point out in my day that the reaction that carried his name was ordered as the Corey-Posner-Whitesides-House reaction and not in the lesser order mentioned in the article.
