DescriptionAntonio Bini of Brooklyn applied for a patent for the mandoline-banjo in 1886, assigning it to August Pollmann. The invention was awarded U.S. Patent number 362,417 in 1887. As Bini stated, “The object of my invention is to provide a mandolin which is so constructed that a great number of tones can be produced, and the same played either in the same manner as a banjo or as a mandolin, combining thereby the advantages of both instruments in one.” Bini was the son of the first Italian luthier in New York, Joseph Bini, who immigrated in the 1840s and played guitar at P. T. Barnum’s American Museum. Antonio Bini was listed as a musical instrument or guitar maker in all census and directory listings from the 1870s through 1910, so it is likely that he was the manufacturer for these instruments on behalf of Pollmann, but they were sold only with Pollmann’s name.
