Marie Alice Heine was an American-born Princess consort of Monaco, by marriage to Prince Albert I of Monaco. Marcel Proust used her as a model for the Princesse de Luxembourg in his novel, In Search of Lost Time. Her first husband was the Duke of Richelieu, and one of the titles of her second husband was Duke of Mazarin; she was thus unique in bearing the titles of both Cardinal Richelieu and Cardinal Mazarin.

Albert I was Prince of Monaco from 10 September 1889 until his death in 1922. He devoted much of his life to oceanography, exploration and science. Alongside his expeditions, Albert I made reforms on political, economic and social levels, bestowing a constitution on the principality in 1911.
