Giovanni Battista Pergolesi (January 4, 1710 Jesi - March 16, 1736 Pozzuoli), Italian composer, better known as Jean-Baptiste Pergolèse.
The rose in commerce is generally listed as a Portland and attributed to Moreau; however, it does not re-bloom and shows typical Gallica characteristics. Neither the Gallica nor the Portland was in Sangerhausen or L'Haÿ collections early in the 20th century. The current rose was probably identified as 'Pergolèse' and re-introduced in the 1940s.
