|Marie-Étienne Nitot (1750-1809) settled in Paris in 1780 after having served his apprenticeship at Auber, then jeweller to Queen Marie-Antoinette. His aristocratic clientele remained loyal to him until the French Revolution in 1789.|
He later became the official jeweller of Napoleon in 1802. Nitot created the jewellery that would offer the French Empire it's splendor and power.
|The jewellery for Napoleon’s wedding to Joséphine de Beauharnais, and later to Marie Louise de Habsburg-Lorraine, was created by Nitot. He designed and set Napoleon’s coronation crown, the hilt of his sword as well as many other pieces for the court.|
François Regnault Nitot took over his father’s jewellery House on his death in 1809 and continued his activity until the fall of the Empire in 1815. Napoleon’s exile caused Nitot, a fervent royalist, to withdraw from the jewellery House, selling the business to his foreman.
