Pierre Marie François de Sales Baillot (1 October 1771 – 15 September 1842) was a French violinist and composer born in Passy. He studied the violin under Giovanni Battista Viotti and taught at the Paris Conservatoire together with Pierre Rode (also a pupil of Viotti) and Rodolphe Kreutzer, who wrote the conservatoire's official violin method (published in the early 19th century). He was sole author of the instructional L'art du violon (1834). Baillot's teachings had a profound influence on technical and musical development in an age in which virtuosity was openly encouraged. He was leader of the Paris Opéra, gave solo recitals and was a notable performer of chamber music. He died in Paris in 1842.
Pierre Marie François de Sales Baillot, who was associated with Rode and Kreutzer in the compilation of the celebrated "Methode du Violon," was born at Passy, near Paris, in 1771, and became one of the most excellent violinists that France ever produced. His eminence in his profession was not obtained without a long struggle against great difficulties, for at the age of twelve he lost his father, who had kept a school, and became dependent upon friends for his education. His musical talent was remarkable at an early age, and he received his first instruction from an Italian named Polidori. At the age of nine he was placed under a French teacher named Sainte-Marie, whose training gave him the severe state and methodical qualities by which his playing was always distinguished.
His love for his instrument was greatly augmented when, at the age of ten, he heard Viotti play one of his concertos, and from that day the great violinist became his model. When his father died a year or two later, the intendant of Corsica, M. de Boucheporn, sent him, with his own children, to Rome, where he was placed with Pollani, a pupil of Nardini, under whom he made rapid progress, and soon began to play in public. He was, however, unable to follow directly in the path of his profession, and for five years he travelled with his benefactor, acting as private secretary, and securing but little time for his violin playing.
