content: Nineteenth-century inventors of improved school apparatus often collected testimonials from teachers and administrators who would attest to the value of their inventions. This collection of documents includes business documents and correspondence relating to Gould’s Patent Arithmetical Frame, a device patented by Henry K. Bugbee and then improved by John Gould. The lists of potential customers and testimonial letters date from the years 1880 to 1893. At least from 1885, Gould was in Chatham, New Jersey, which is where he was when he received his patent in 1882.
