On the 17th August, as part of Heritage Week we at The Maria Edgeworth Centre will perform a simulation of R. L. Edgeworth's pioneering telegraphic message between Dublin and Galway in 1803. The message will be relayed using a model of Edgeworth's semaphore, from the Irish Museum of Modern Art at the Royal Hospital Kilmainham, and received at the Computer & Communications Museum Ireland, National University of Galway Campus. Members of the public can attend in person, register to join on line or visit the Maria Edgeworth Centre in Edgeworthstown, Co. Longford. Following registration you will receive the link to join the event. This is a unique event that should not be missed for all those with a hunger for history and knowledge. Born in 1744, Richard Lovell Edgeworth was seven years old when his curiosity in science first began to awaken. He was Anglo-Irish inventor, educationalist, writer and politician living in Edgeworthstown, Co Longford . He made many important contributions to science, education, and technology. One of his inventions was the optical telegraph, sometimes called a 'tellograph'. The device was an early form of visual communication, used long before electric telegraphs and telephones were invented. Edgeworth's optical telegraph sent messages over long distances using visual signals. His system was designed mainly for military and commercial use. In 1803 R.L. Edgeworth demonstrated his system by sending a message from The Royal Hospital, Kilmainham, Dublin to Williams St. in Galway. If you want additional details we can be reached at 0872241351

The Edgeworth Telegraphic event of 1803 was a unique event at the time and was the catalyst for the modern telecommunications systems we have today. When Edgeworth's son relayed his message from Northern Ireland to Scotland it was believed to be the first time a message was sent across a body of water.
