Frère Jacques Beaulieu (French pronunciation: ​[fʁɛʁ ʒɑk boljø]); 1651–1720), also known as Frère Jacques Baulot, was a travelling lithotomist with scant knowledge of anatomy and was also a Dominican friar. Beaulieu performed the frequently deadly procedure in France into the early 18th century. Some have suggested that Frère Jacques was instead written to mock the Jacobin monks of France (Jacobins are what the Dominicans are called in Paris).
