Louis-Claude Daquin (1694 – 1772) was a French composer of Jewish birth writing in the Baroque and Galant styles. He was a virtuoso organist and harpsichordist. He was born in Paris, to a converted Jewish family from Carpentras originating from Italy (where their name was D'Acquino). One of his great-uncles was a professor of Hebrew at the College de France. Daquin was a musical child prodigy, for he performed for the court of King Louis XIV at the age of six. He was for a while a pupil of Louis Marchand. At the age of 12, he became organist at the Sainte-Chapelle, and in the following year took a similar post at the church of the Petit St. Antoine.
In 1727 Daquin was appointed organist at the church of St. Paul in Paris, besting Jean-Philippe Rameau for the job. Five years later he became organist, succeeding Louis Marchand, at the Cordeliers. In 1739 he became organist to the king. In 1755 he succeeded Antoine Calvière as titular organist at the cathedral of Notre-Dame de Paris. By reputation a dazzling performer at the keyboard, Daquin was much appreciated by the aristocracy and his great expertise at the organ drew considerable crowds to hear him. As a virtuoso organist and harpsichordist, he was known for his "unfaltering precision and evenness".
