Louis II, Prince of Monaco
On 26 June 1922, Prince Albert I died in Paris. Louis Grimaldi ascended to the throne as Louis II, Prince of Monaco. While his reign never achieved the grandeur of his father, Louis II left an indelible imprint on the tiny principality. In 1924 the Monaco Football Club was formed and in 1929, the first Grand Prix of Monaco automobile race was held, won by Charles Grover (aka "Williams") driving a Bugatti painted in what would become the famous British racing green color. He collected artefacts belonging to Napoleon I which are now assembled and displayed in the Napoleon Museum attached to the Royal Palace in Monte Carlo.
Albert I, Prince of Monaco
On 10 September 1889, Albert ascended the throne of Monaco on the death of his father. That same year in Paris, on 30 October, he married the Dowager Duchess de Richelieu, née Marie Alice Heine (1858–1925). The American daughter of a New Orleans building contractor of German-Jewish descent, Alice Heine had married the Duc de Richelieu but had been widowed by age 21 and left with a young son, Armand. Her marriage to Prince Albert proved an equal blessing for him and the tiny principality of Monaco, since Alice brought a strong business acumen, well in advance of her youth. Having helped put her husband's principality on a sound financial footing, she would devote her energies to making Monaco one of Europe's great cultural centers, with an opera, theater, and a ballet under the direction of the famed Russian impresario Serge Diaghilev.
