An instrument importer and dealer, Charles Bruno immigrated from Germany to Macon, Georgia in 1832. In 1834, Bruno moved to New York where he probably worked as a clerk or salesman for several years before being listed as a book seller in 1837. In 1838 Bruno formed a partnership with Christian F. Martin. His book shop on Fulton Street most likely served as a retail outlet for Martin's guitars. When Bruno & Martin dissolved their partnership in 1839, Bruno left New York for several years.
On his return to New York Bruno established the partnership Bruno & Cargill from 1851 to 1853, and then Bruno, Weissenborn and Company with Herman W. Weissenborn (this was not the designer of the Weissenborn lap steel guitar - that was Hermann C. Weissenborn) 1854 to 1857.
