How many people were involved in making the electric telegraph?

The development of the electric telegraph involved several key figures, most notably Samuel Morse and Alfred Vail, who worked together to create the Morse Code system and improve the telegraph technology in the 1830s and 1840s. Other inventors, such as Charles Wheatstone and William Cooke in the UK, also contributed to its development. While a precise number of people involved is difficult to determine, the innovation was a collaborative effort among multiple inventors and engineers across different countries.
