Public Demonstration. Morse and Alfred Vail built the first telegraph at the Speedwell Ironworks in Morristown on January 6, 1838. The first public demonstration occurred five days later on January 11, 1838. This event is recognized as an early step toward the Information Age. The Speedwell Ironworks is a National Historic Landmark and museum at the site where the electric telegraph was first presented to the public.

The Morse system and its associated code became the archetype of their category of telegraphy.
