Etienne-Lucien Blerzy entered a maker’s mark for: bijouterie: le gros bijou d’or in 1801/02 from 118 rue du Coq St-Honoré. He died there in 1808. Goldsmiths such as Vachette, Montauban and Blerzy, whose elder brother, Joseph-Etienne Blerzy, had been one of the most prolific gold box makers of the Ancien Régime, supplied the Emperor and his family with snuff boxes on which to mount their ciphers or portraits. Etienne-Lucien Blerzy is known to have supplied boxes to both Marguerit, official jeweller to Napoleon who sold the Emperor one hundred gold portrait boxes in 1806, and as with this box, Gibert on the quai Voltaire. Napoleon and members of his family found them a useful means of expressing Imperial favour. Napoleon Bonaparte 1769-1821, a French military and political leader, rose to prominence during the latter stages of the French Revolution and from 1804 was styled Napoleon I, Emperor of the French from 1804 to 1815. His reign lasted until 22 June 1815 when he was defeated at the Battle of Waterloo, exiled and imprisoned on the island of Saint Helena, where he died on 5 May 1821. For a very similar box by Blerzy see Christie's, London, 28 May 2002, lot 225.
