Daniel Drawbaugh
註釋This book examines the works of Daniel Drawbaugh, known as the Edison of the Cumberland Valley. Many authorities in his day vouched for Drawbaugh’s talking machine and for his claim to being the original inventor of the telephone. Drawbaugh’s claims provided the courts with the most exciting, and the most futile, litigation in the history of telephone patents. For eight years, during the 1880’s, Drawbaugh fought the American Bell Telephone Company in an astoundingly close battle. By a one-vote margin, Drawbaugh missed being officially recognized as the inventor of the telephone.
