The Center on Halsted, 3656 N. Halsted St., will host a fireside chat with Marge Summit, a vocal member of the Chicago LGBT community best known for owning a now shuttered bar under the Addison L stop called His 'N Hers. 

She will be interviewed about the history of leather. The event is produced by Leatherman Douglas O'Keefe and Mistress Joanne Gaddy.

A $5 donation is suggested for the event on Wednesday, Oct. 2 from 7:30 p.m. to 10 p.m.
