The Kay Musical Instrument Company is an American musical instrument manufacturer established in 1931 by namesake Henry “Kay” Kuhrmeyer and based in Chicago, Illinois.  It was formed when Kuhrmeyer, with the support of his financial backers, bought out the instrument manufacturer Stromberg-Voisinet. They produced guitars, mandolins, banjos, and ukuleles.  The Kay company was purchased by the Seeburg Corporation, a jukebox manufacturer, in 1965.
