Grab a cocktail, grub and a gay-and-lesbian history lecture at the Chicago History Museum’s “Out at CHM” lecture series kick-off event Thursday. The first lecture of the three-part series—titled “Sexual Politics: From the Lavender Scare to Larry Craig”—will be an examination of the history of how the sexuality of gay men has emerged as a hot-button topic in American politics. “We try to keep it so it’s the topic in mind, so it’s geared toward what people are talking about in their homes, ” says Chicago Museum spokesperson Melissa Hayes. This lecture marks the fifth year for the “Out at CHM” series, a program brought to the public by The Center on Halsted and The Chicago History Museum as a continuing effort to bring LGBT history to Chicago’s public. “Gays and lesbians in Chicago is such a part of this city’s history,” Hayes says, “and try to tell that history from all different perspectives.”
