Ernst Heinrich Roth (1877–1948), also often referred to as Ernst Heinrich Roth I to distinguish him from later family members of the same name, was a German luthier and master of a large and successful violin-making workshop in the East German town of Markneukirchen, near the current border with the Czech Republic. He was the most important and distinguished figure in a whole dynasty of Roth luthiers active in Germany over many generations and to this day.
