Etymology of TACHOGRAPH
The word "tachograph" has its roots in Greek and French. The term "tachograph" combines two Greek words: "tachos", meaning "speed", and "graphos", meaning "writer" or "recorder". It was coined in the late 19th century by a French engineer named Edouard-Léon Scott de Martinville.
The original concept of tachographs was developed by Scott de Martinville in 1857, who created a device called the "phonautograph". It was designed to visually record sound waves using a stylus and a rotating cylinder covered in soot. However, the phonautograph was not specifically intended for measuring speed.
The modern tachograph as we know it today, which records and measures the speed, distance, and driving time of vehicles, was invented by a German engineer named Paul Julius Gottlieb Nipkow in 1881.
