French violin maker Sébastien Auguste Deroux was born in 1848 in Mirecourt, France and died in Paris in 1919. He studied with his father, Georges Deroux ("Deroux père," 1822-1889), whose workshop trained several other celebrated luthiers, including Emile Mennesson, Alfred Ebsworth Hill, and Louis Morizot. After moving to Lyon to work for Hippolyte Silvestre in 1866, Auguste Deroux settled in Paris in 1873, where he worked for Claude Augustin Miremont, before establishing his own business in 1884. Deroux's grandsons Roger (b. 1901) and Max Stanislas Millant (1903-2005) trained with him to become outstanding makers themselves, founding the famous firm Roger & Max Millant in Paris in 1923, one of the most important French ateliers of the 20th century. The family's long line of luthiers continued with Max's son, renowned bow expert Bernard Millant (1929-2017). Deroux's famous rosin recipe, created in 1884 and produced by his grandsons as Colophane Millant-Deroux, continues as a popular rosin today.
