Hoerr, H & F

Henry & Franz Hoerr established the firm of H & F Hoerr in Toronto, Canada, in 1891.  In 1895, H & F Hoerr patented the “Tone Arrangement of Piano Strings”, a peculiar devise that added extra strings and bridges to increase the overall tone of the instrument. 


There is very little historical information about H & F Hoerr.  1897 Henry Hoerr assigned his interest in the firm to Franz Hoerr, making Franz Hoerr the sole owner of the firm.  There is no mention of the firm after 1897.
