French sculptor, son of Nicolas Guillain (c. 1560-1639), a wood-carver from Cambrai. He was trained by his father and studied with Alessandro Algardi
in Rome, returning to France in 1612; he went on to become one of the leading sculptors of the reign of Louis XIII, rivalled only by Jacques Sarazin. Brought up in the craftsmanlike and realist traditions of late 16th-century French sculpture, he absorbed the influences of the Italian Baroque and through his pupils Franois Anguier and Michel Anguier helped to form the French classical style in sculpture. He collaborated with his father on a number of works, including a fountain (1613; destroyed) for the chteau of Coulommiers, Seine-et-Marne, and the praying figures of Prsident Jeannin and his wife Anne Guniot (marble, 1626-27; Autun Cathedral).
His early independent works include the praying funerary effigy of Henri de Montpensier (marble, 1624-26) in the Sainte-Chapelle at Champigny-sur-Veude, Indre-et-Loire; the praying figures of Charles Bailly (reduced bust, marble, 1628; Versailles, Chteau), Bailly s widow Chrtienne Leclerc (marble, 1628; Paris, Louvre) and Charlotte-Catherine de la Tremoille, Princesse de Cond (marble, 1629; Paris, Louvre). They reveal the development of a more fluid technique, broader composition and suppler gestures. He also produced at this time a number of tombs decorated with busts of the deceased, surviving examples including those of Franois de Montholon (marble, 1623; Versailles, Chteau) and Robert le Roux de Tilly (marble, 1639; Acquigny, Chteau), which is decorated with three funerary genii, evoking the art of Franois Du Quesnoy.
His main works were the statues for the monument of the Pont au Change.
They were commissioned by the City of Paris to commemorate the presentation of the future Louis XIV to the people on April 21st, 1643.
