Frère Jacques Beaulieu

Frère Jacques Beaulieu, OP ; 1651–1720), also known as Frère Jacques Baulot, was a Dominican friar and travelling lithotomist with scant knowledge of anatomy. Beaulieu performed the frequently-deadly procedure in France into the early 18th century.
The urologic community often claims Beaulieu is subject of the French nursery rhyme Frère Jacques, but this is not well-established. A possible connection between Frère Jacques and Beaulieu, as claimed by Irvine Loudon and many others, was explored by J. P. Ganem and C. C. Carson without finding any evidence for a connection.
Some have suggested that Frère Jacques was instead written to mock the Jacobin monks of France.
