Cooper Hewitt says...

A sculptor and engraver who worked primarily in Paris, Lepautre won the Prix de Rome in 1684. His first appointment to a post of importance as engraver and designer to the king came in 1699 when he entered the service of Jules Hardouin Mansart, the king's chief architect. In 1701 he was named "sculpteur des bâtiments du roi". Together with Mansart, he designed fountains and pools at Saint-Cloud with Jules Hardouin Mansart. From 1708 to 1710 he created the interior plans and elevations for the Chapel at Versailles also by Mansart (Chapel begun in 1689). Lepautre's own works included designs for tables, chimneypieces, garden furniture, doors and wall decorations. [Bio from ULAN] Le Pautre was the son of Jean Lepautre (1618-1682) and Marguerite Gastelier.
