BELLOY, DORMONT DE, the name assumed by PIERRE LAURENT BUIRETTE (I 7 2 7-I 775), French dramatist. He was born at Saint-Flour, in Auvergne, on Nov. 17, 1727, and educated for the bar. To escape from a profession he disliked he joined a troupe of comedians playing in the courts of the northern sover eigns. He returned to Paris with Zelrnire (1762), a fantastic drama which met with great success. This was followed in 1765 by the patriotic play, Le Siege de Calais, which had a sensational success, and was followed by Gaston et Bayard (i771), Pedro le cruel (17 7 2) and Gabrielle de V ergy (17 7 7) . None of these attained the success of the earlier plays. De Belloy died on March 5, His death is said to have been hastened by disappointment.
