Early telephone in Twain’s home

• Mark Twain (Samuel Clemens) is widely noted as one of the first private individuals and one of the first writers to have a telephone installed in his home soon after Alexander Graham Bell’s invention was introduced in the late 1870s.

• Biographical accounts of Twain’s life and his enthusiasm for new inventions consistently mention that he adopted the telephone very early, well before it became common in ordinary households.
