This new exhibit at the Morgan Library & Museum has an interesting connection to those in the 9/11 community. Bill Keegan, a retired Port Authority Police lieutenant, served as the PAPD Night Operations Commander at the WTC site and he has contributed his diary to the collection on display. His diary describes line by line what he was doing on a daily basis in the recovery effort. The day displayed is Christmas Eve, 2001 - when he was working at the site and also preparing to go to Midnight Mass. Lt. Steve Mona, NYPD (Ret) and H.E.A.R.T.
