It seems that is correct. His partnership agreements with Hubbard and Sanders in 75 says American as does the patent application from Feb 14, 1876 and later corporate filings (76,77). So what do we call him? Shall we use a neutral source? http://www.britannica.com/biography/Alexander-Graham-Bell If the Brits aren't claiming him, I don't know how Canada can? We've exposed a few myths today however, thank you.
