What newspaper did Thomas Edison publish while working as a teenage telegraph operator?

Thomas Edison published The Grand Trunk Herald while working as a teenage telegraph operator.

Edison produced the small newspaper during the 1860s while employed on the Grand Trunk Railway. He reportedly wrote, printed, and sold copies to passengers traveling between Port Huron and Detroit. The paper combined railway news with brief reports gathered from telegraph communications.

This episode illustrates how Edison used access to railway equipment and telegraph lines to experiment with publishing and communication. It also helped establish his reputation for initiative at a very young age.

The Grand Trunk Herald was not a major city newspaper and did not operate like a modern daily publication. Its importance comes from its connection to Edison’s early working life, before he became a full-time inventor and industrialist.
