Long believed to be a "forgotten classic" house cocktail of the Seelbach Hotel in Louisville Kentucky, it is now known to be a fabrication of the then bartender at the Seelbach hotel, Adam Seger. It was around 1995 when the fledgling bartender tried to dig through the hotels past to see if he could find a "specialty of the house", but never did. So instead he created this cocktail, and then a fanciful, and plausible, story around it having been created there in 1912.
