French historian, art historian and poet.
A Member of the French School of Rome in 1882, he worked there on Italian humanism of the sixteenth century. In 1886 he was attached to the Museum in the Palace of Versailles and became curator in 1892, founding a chair of art history within the École du Louvre in 1910, then retiring to the Musée Jacquemart-André in 1920. He was elected a member of the Académie française in 1922.
His activities in the museum of Versailles were crucial, since they contributed greatly to modernisation and to restoring the collections, including the furniture, which had been dispersed during the French Revolution. He played a role in the preparations for the Treaty of Versailles, which took place in the Palace in June 1919.
Pierre de Nolhac left a substantial body of work largely devoted to history, especially to Renaissance humanism. During his stay at the French School of Rome (1882-1885), he discovered unpublished manuscripts of Petrarch in the Vatican library, and the discovery helped advance knowledge about his subject. His monograph on Fulvio Orsini is still authoritative. He also devoted several books to Queen Marie-Antoinette at Versailles. His work as a poet was recognised in his own time, notably by his friend, the Italian poet Gabriele d’Annunzio.
The central library of Versailles has many manuscripts of major works by Pierre de Nolhac, including Erasmus and Italy, Queen Marie Antoinette, Nattier, Louis XV and Marie Leszczynska. Also available are the original of his 1924 acceptance speech to the Académie française and his very extensive correspondence with figures as diverse as Marcel Proust, Henri Bergson, Leconte de Lisle, Ernest Renan, or Mussolini Liautey.
He was a prolific writer.
He is the father of the painter Henri de Nolhac.
He died 31 January 1936.
