In 1827 Mr. Rocher and his cousin, Baptise Noury, established a jewellery shop in Paris which, by 1850, had been taken over by Noury. His nephew, Georges Maubboussin, joined the firm, assuming control in 1896. The House of Mauboussin contributed exhibits to all major international exhibitions in the first half of the 20th century including Milan in 1923 and 1924; New York in 1924 and 1939; Strasbourg in 1924; and Paris in 1925, 1931 and 1937. They were awarded at the Grand Prix at the 1925 Exposition des Arts Decoratifs in Paris and, for his contributions to the world of jewellery Georges Mauboussin, was given the “Legion d’Honneur”. The firm opened branches in London and Buenos Aires, which have subsequently closed. In October 1929, they opened an office in New York. Due to difficult times, they sold there stock to the jeweller Trabery & Hoeffer along with the right to use their name. All jewellery retailed under this contract was signed “Trabert & Hoeffer Inc. – Mauboussin”. This relationship lasted until the 1950s. The firm is currently located at 20, Place Vendome. In 2002, Dominique Fremony, a Swiss businessman, acquired a majority of the firm with Patrick Mauboussin remaining involved in the creation of the jewellery.
