On this installment of ST, we learn about a new exhibit at the Gilcrease Museum, "Chocolate: The Exhibition," which will be on view through January 8th. Our guest is Gary Feinman, the MacArthur Curator of Mesoamerican, Central American, and East Asian Anthropology at The Field Museum in Chicago; he's one of the curators of this interesting show, which was actually created over a decade ago.

On this edition of StudioTulsa, we speak with Doug Henderson, an architectural photographer based here in Tulsa who has photographed, starting back in 2010, many different forts and castles along the coast of West Africa where, from the 1600s to the early 1800s, European traders imprisoned slaves until ships could carry them to the New World. Through these grim and rather under-documented structures, more than 12 million people passed in their shameful journey to slavery.

On this edition of ST, we speak with Kristen T. Oertel, the Barnard Associate Professor of 19th Century American History here at TU.

On this edition of ST, we welcome Linda Barnickel, a former Tulsa resident with master's degrees from the University of Wisconsin-Madison and The Ohio State University who now works as an archivist, researcher, and writer in Nashville. She's also the author of "Milliken's Bend: A Civil War Battle in History and Memory" (LSU Press). In June of 1863, on the banks of the mighty Mississippi, at Milliken's Bend, Louisiana, a Union force composed mainly of former slaves met their Confederate foes in one of the most vicious --- and most "hand-to-hand" --- small battles of the entire Civil War.

The issue of slavery was, of course, at the heart of the American Civil War --- but have you ever wondered why this country fought a four-year, deeply tragic war over the issue, while many other nations (during basically the same historical period) did away with slavery without going to war? We're pleased to welcome to our show the historian Thomas Fleming, who has written more than 50 books and often appears as a commentator on PBS, A&E, and the History Channel.
