Ronalds
From GATE
Francis Ronalds (1788–1873) was a British scientist and inventor known for his contributions to the fields of electricity and meteorology. He is best known for his work on the development of the first practical and operational electric telegraph system, which predated Samuel Morse's more famous telegraph system.
Ronalds began working on his electric telegraph in the early 19th century and successfully demonstrated a working model in 1816. His telegraph system used static electricity and synchronized clocks to send messages over long distances using electrical signals. However, his invention did not receive the recognition or widespread adoption it deserved at the time.
