Saul Bellow would have turned 100 next month. To celebrate the centennial of this great American novelist, a number of writers will read from his work at the the Kauffman Concert Hall at 92Y on Thursday night, including Martin Amis, Jeffrey Eugenides and Ian McEwan. Zachary Leader, who just published The Life of Saul Bellow, will also read, as will Janis Bellow, the late author’s wife. Bellow died in 2005. Jill Krementz photographed him a number of times throughout his life. Below are some of the photos she took, accompanied by her own captions.
