Born in Paris, he was a brilliant depicter of light comedy which reflected the tastes and manners of French society during the regency of the Duke of Orleans and, later, early reign of King Louis XV.
Two pictures painted by Lancret and exhibited on the Place Dauphine had a great success, which laid the foundation of his fortune, and, it is said, estranged Watteau, who had been complimented as their author.
In drawing and in painting his touch is often considered intelligent but dry; art historian Michael Levey remarked that Lancret was 'no poet but a charming essayist'.
The work's flowing lines, Rococoesque harmony of pastel colours, painterly style and charming subject matter (of a wide eyed young girl, surrounded by her happy family and natural, yet un-threatening setting, trying her first taste of coffee) are seen[2] to display a delicate sense of vitality and freshness that anticipate the works of both Thomas Gainsborough and Jean-Honoré Fragonard.
Supposedly Lancret was induced to marry her after finding her and her dying mother living in poverty in an attic room and hearing that the daughter was soon to be compelled to enter a convent.
