Short answers, pulled from the story.
Pierre Lescot was born in Paris during the early 1500s. He did not emerge from a family of masons or builders with practical experience but instead came from a noble family where his father held the title of seigneur.
King Francis I of France appointed Pierre Lescot as the architect responsible for building projects at the Palais du Louvre. A contract dated 1551 formalized this role after the king chose Lescot over an alternative design proposed by Sebastiano Serlio.
Only the west side and part of the south side of the courtyard were completed before Pierre Lescot died. Constructed between 1546 and 1551, the Lescot Wing stands as the present southwest wing of the Cour Carré.
All known works by Pierre Lescot feature sculptural decoration by Trebatti and Jean Goujon. These artists collaborated with him on the Louvre project and their work appears prominently within the Salle des Caryatides.
Pierre Lescot designed the Fontaine des Innocents between 1547 and 1549. This fountain replaced an ancient public one for the entry of Henry II into Paris in 1549.
