I find it really interesting that Hanna Gray was on the Harvard Corporation board in 2001 and the biggest supporter of Summers and pushed for his choice over then Michigan President Bollinger who was the other main contender.
She really disliked what she perceived as the lack of rigor in the outgoing President Neil Rudenstine’s approach and his almost exclusive focus on fundraising 
Do you think Summers would succeed in Chicago?. Clearly his tenure at Harvard was less than successful
He was brought in to revamp the College and revitalize Science among other priorities
