Jean-Jacques Lequeu (September 14, 1757 – March 28, 1826) was a French draughtsman and architect.
Born in Rouen, he won a scholarship to go to Paris.
Following the French Revolution Lequeu's architectural career never took off.
He spent time preparing the Architecture Civile, a book intended for publication, but which was never published.
He became a civil servant working as a surveyor and a cartographer until his retirement in 1815.
Lequeu is now considered part of the period of "visionary architecture" which developed in the period leading up to the French Revolution.
This was directly influenced by the great competitions organised by the École des Beaux-Arts.
These competitions encouraged entries comprising massive buildings unfettered by budgetary constraints.
This resulted in scores of designs for vast and impressive buildings which had little connection with the real world and remained "paper architecture".
Some of them are pornographic and are kept in the Enfer of the library.
They include a cow barn in the shape of an Assyrian bovine; an erotic garden folly called the Hammock of Love, replete with a copulating couple; a priapic fountain in a Gothic tabernacle and two self-portraits in drag.
Most of these drawings have been reproduced in Duboy's book in 1986.
More recently, an exhibition took place at the Musee du Petit-Palais (Paris) in December 2018.
Lequeu's historiography has led to a deep reflection.
It is only at the middle of the 20th century that he is rediscovered by the Viennese historian Emil Kaufmann.
This pioneering work takes the controversial view that Lequeu's work is partially the result of a deliberate manipulation involving Marcel Duchamp.
As early as 1987, the theorist and historian of architecture Joseph Rykwert, in a review of DuboĂż's book, underlined the weakness of his scientific justification which mixed fact, fiction, fancy, incongruous comparisons and the most unverifiable conjectures.
According to Elisa Boeri, “Assumptions that Duchamp contributed to the possible manipulation of Lequeu's legacy at the National Library now appear to be chimerical”.
American art historian and art critic James Elkins considers that this is a deliberate hoax.There is obviously ambiguity surrounding the relations of Lequeu to Surrealism.
A kind of retrospective illusion could lead us to see several of Lequeu's drawings through the prism of the paintings by De Chirico, Magritte or Delvaux.
