Despite the success of his musical debut, his career as a composer was short-lived. Boisselot had already assumed the management of his family business in Marseille and Barcelona, following the death of his brother Louis-Constantin (1809–1850), himself a successor to their father Jean-Louis (1782–1847), music publisher and musical-instrument manufacturer in Montpellier and Marseille. His achievements brought him many awards at exhibitions, such as one silver medal at the Paris Exposition of 1839, one gold medal at the French Industrial Exposition of 1844 and again at the London Great Exhibition of 1851. The quality of his grand pianos at home granted him a first class medal at the Exposition Universelle (1855), where his products were among the best of France and Spain.
