Weymann Guitars is an American manufacturing company of musical instruments. Established in 1864 in Philadelphia, Weymann is one of the oldest instrument companies in the country. Originally founded as "H. A. Weymann and Son" by German immigrant Henry Arnold Weymann, Weymann patented the mandolute and also developed the first "Jumbo" body acoustic guitar produced during the turn of the century, nearly two decades before competitors in the instrument industry.[1]
