By night, he works as a Chicago historian and tour guide, with a specialty in ghostlore, crime, and weird stuff. He built a reputation for sticking to accurate historical information (something not many people do on ghost tours) and keeping a skeptical head (probably to more of an extent than he should have - people don't always WANT to hear that certain stories have no basis in fact!). His most recent ghost book is THE GHOSTS OF CHICAGO (Llewellyn Worldwide, September 2013), and he is now at work on a book on Abraham Lincoln ghostlore.
His main homepage is adamselzer.com
He is available for library talks, school visits, private ghost tours, and more. Here's the front and back of his 2013 business card:
