==History==

While [[typewriterTypewriter]]s are the definitive ancestor of all key-based text entry devices, but the computer keyboard as a device for electromechanical data entry and communication derives largely comes from the utility of two devices: [[teleprinter]]s (or teletypes) and [[keypunch]]es. It was through such devices that modern computer keyboards inherited their layouts.

As early as the 1870s, teleprinter-like devices were used to simultaneously type and transmit [[stock market]] text data from the keyboard across telegraph lines to [[stock ticker machine]]s to be immediately copied and displayed onto [[ticker tape]].{{cn|date=October 2023}} The teleprinter, in its more contemporary form, was developed from 1907 to 1910 by American mechanical engineer [[Charles Krum]] and his son [[Howard Krum|Howard]], with early contributions by electrical engineer [[Frank Pearne]]. Earlier models were developed separately by individuals such as [[Royal Earl House]] and [[Frederick G. Creed]].
