I want to know the answer to the following question:
What expert on Whitehead delivered a lecture at the school to explain Whitehead's ideas?
All the background I'm provided with is that "Wieman's lecture was so brilliant that he was promptly hired to the faculty and taught there for twenty years, and for at least thirty years afterward Chicago's Divinity School was closely associated with Whitehead's thought.". Is that enough to answer the question?
