Paul Louis Boeswillwald (October 22, 1844, in Paris – July 17, 1931, in Paris[1]) was a French architect and art historian.
Son of the architect Émile Boeswillwald and father of the painter Émile Artus Boeswillwald, he was a pupil of his father and Charles Laisné and collaborated with Eugène Viollet-le-Duc on the restoration of the ramparts of the historic Fortified City of Carcassonne since 1879.[2]
Like his father, he was an inspector of historical monuments. He succeeded his father in the restoration of the Saint-Étienne cathedral in Toul. He was also a professor and had as students Max Sainsaulieu and Paul Vorin.[3]
A diocesan architect of Bourges, he joined the commission for historical monuments on March 26, 1885, was appointed inspector general on December 21, 1895, to replace his father, and retired on February 11, 1929.
His son portrayed him in 1895. This work exhibited at the Salon of French Artists in 1895 was donated, in 1982, to the museum of Nogent-sur-Seine.
