Germain Boffrand was a French architect. A pupil of Jules Hardouin-Mansart, Germain Boffrand was one of the main creators of the precursor to Rococo called the style Régence, and in his interiors, of the Rococo itself. In his exteriors he held to a monumental Late Baroque classicism with some innovations in spatial planning that were exceptional in France His major commissions, culminating in his interiors at the Hôtel de Soubise, were memorialised in his treatise Livre d'architecture, published in 1745, which served to disseminate the French "Louis XV" style throughout Europe.
