S. L. Kotar and J. E. Gessler's first writing success was an episode of the television series GUNSMOKE. The episode, "Kitty's Love Affair," guest-starred Richard Kiley as a gunfighter who saves Kitty's life and then becomes romantically involved with her. This was the highest-rated episode in the series' 20-year history. They published an iconoclastic Civil War magazine called "The Kepi" for many years, specializing in new historical perspectives of the battles and leaders as well as presenting detailed articles on life in the 1860's. Their published works include a detailed account of the series starring Darren McGavin, "Riverboat: The Evolution of a Television Series, 1959-1961" and historical non-fiction texts including, "The Steamboat Era: A History of Fulton's Folly on American Rivers, 1807-1860," "Ballooning: A History, 1782-1900," "The Rise of the American Circus, 1716-1899," "Smallpox: A History," and a cardiology textbook, "The Complete Guide to Ambulatory Cardiac Monitoring and Full Disclosure Telemetry." Their book, "Cholera: A History" is due out later in 2013 and they are currently working on "Yellow Fever: A History," due out in 2014. Outside of writing and cardiology, their main interest is baseball; they are close friends with Whitey Herzog, the great Hall of Fame manager, who inspired them to move to St. Louis and they have rooted for the Pittsburgh Pirates for many years.
