It was Edward A Calehan who invented the first stock telegraph in the year 1867. But prior to what Calehan had invented, in 1794, a non-electric telegraph was invented by Claude Chappe which was used as visual system. Calehan was actually working for the American telegraph Company when Calehan's invention of the stock telegraph was invented in the year 1867. When Calehan invented his new invention it made an interesting sound which influenced the name Stock Ticker. History speaks more about Calehan as the man who invented stock ticker though Thomas Edision had tried the invention years younger to he invented the electric bulb. Hope this helps.
