FALLS CHURCH, Va. – This year marks the 150th anniversary of Alexander Graham Bell’s most famous invention: the telephone. While scientific history is mired in controversy over who actually devised the first electronic speech-transmitting device, with a number of contenders in the fray, it was Bell who received the US patent for the telephone, on March 7, 1876. In recognition of Bell’s world-changing invention, Quinn’s has included several significant early documents and other ephemera pertaining to the telephone patent dispute in its February 20 Presidential Autograph and Americana Auction.
