Frère Jacques Beaulieu

Frère Jacques Beaulieu, OP (French pronunciation: [fʁɛʁ ʒɑk boljø]); 1651–1720), also known as Frère Jacques Baulot,[1][2] 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.

[3] The urologic community often claims Beaulieu is subject of the French nursery rhyme Frère Jacques (also known in English as Brother John), but this is not well-established.

A possible connection between Frère Jacques and Beaulieu, as claimed by Irvine Loudon[4] and many others, was explored by J. P. Ganem and C. C. Carson [5] without finding any evidence for a connection.

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).
