Professor, urban historian and former broadcast journalist. Just published is my "Real, True Backstories of Old Chicago: As told Day by Day from 1673 to 1925". In it I recount hundreds of the same kinds of Chicago stories as heard in these audio tours, some short and some longer. Right now only available as an Amazon ebook (just search "Backstories of Old Chicago"). Meanwhile watch for me on city streets. I'm the guy who's always saying "guess what happened here?" as I walk with friends.
