Chicago Tribune photo editors Marianne Mather and Robin Daughtridge will talk grifters and gangsters at 4 p.m. Tuesday, October 13, in the Circus Room of the Bone Student Center at Illinois State University.

The duo compiled photographs pulled from the Tribune archives for the publication Gangsters & Grifters: Images from the Archives of the Chicago Tribune. An exhibit based on the book is now on display at Illinois State’s Milner Library on the second floor.

Mather and Daughtridge will discuss their research and discoveries in the monumental collection of 4×5 glass plate and acetate negatives. Normally housed five stories below the Tribune Tower, many of the photos were unpublished and unseen for decades.

The new book features a selection of reprinted photographs from the recent publication of the same name. These images document the crime scene in the city of Chicago during the 1920s and 1930s, as seen through the eyes of the Tribune photographers. Their photographic storytelling captures ordinary people, notorious criminals, new technologies, and a spectrum of moments that define the roles cameras and photo journalists played in documenting the history of a city.
