Thomas Edison, an inventor of the late

1800's, always said that the phonograph was his

only real discovery, the only invention he stumbled

upon rather than deliberately set out to find.  Having

invented it, he then had to find a use for it.  Musical

entertainment was one of the first uses he predicted

for the phonograph, although it was by no means the

only one.  The inventor claimed that it would change

education, politics, and business communication, in

addition to providing entertainment.  Edison also

thought it could be adapted for phonographic books for

people with visual impairments, for the teaching

of public speaking, and for talking clocks.

    It was thought that the phonograph could be

used to save telephone messages, and the ability to

record speech opened up several commercial uses.  

Chief among these was its employment as a dictating

machine for people in business.  A talking machine

could be used to replace the tedious exchange of

letters with the recorded message of the speaker

on a phonograph cylinder.  The inventor hoped that

the cylinder could be sent through the mail with the

ease of a letter.  The advantage was that the recipient

got an exact record of the sender's message as

it was dictated, substituting a sound recording for

correspondence.  The paperless business office

was anticipated well before the advent of personal

computers and modems.

    Edison hoped that the phonograph would transform

office work.  The electric light, telephone,

and typewriter were slowly changing the way business

was conducted in the United States, facilitating the task

of managing the larger business organization of the

late nineteenth century.  When used as a dictating

machine, the phonograph promised to further ease

the burden of business administration by mechanizing

correspondence.  The device that had begun as a

complement to the telephone was now seen as an

adjunct to the typewriter.

    At the same time that Edison was imagining the

phonograph as the ultimate business tool, he also

made a prophetic statement about its future.  “This

machine,” he wrote in 1878, shortly after the clamor

surrounding the invention had died down, “can only be

built on the American principle of interchangeability of

parts, like a sewing machine.”  Edison had grasped

the idea of mass production using standardized parts.
