Cartier would become the unofficial Court Jewellers to the Duke and Duchess of Windsor while they lived in exile in Paris. Having already had Wallis' engagement ring made by the jewellers, he returned to Cartier after the Ednam Lodge robbery of 1946 to rebuild Wallis' collection, using his insurance money from Lloyds of London. Edward claimed the Cats were to guard her new collection. In total, Cartier would create nine Great Cat pieces for Wallis over the years.
