Albert I, Prince of Monaco

Albert I (Albert Honoré Charles Grimaldi; 13 November 1848 – 26 June 1922) 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's reign oversaw major reforms on political, social, and economic levels, with the Monégasque Revolution leading to the end of absolute monarchy and his promulgation of a constitution in 1911.

Born on 13 November 1848 in Paris, France, the son of Prince Charles III (1818–1889), and Countess Antoinette Ghislaine de Merode (1828–1864), a Belgian noblewoman, maternal aunt of Donna Maria Vittoria dal Pozzo, Princess della Cisterna, Duchess consort of Aosta and Queen consort of Spain.

As a young man, Prince Albert served in the Spanish Navy as a navigator. During the Franco-Prussian War, he joined the French Navy where he was awarded the Legion of Honor. In addition to his interest in oceanographic studies, Albert had a keen interest in the origins of man and in Paris, he founded the "Institute for Human Paleontology" that was responsible for a number of archeological digs. The "Grimaldi Man" found in the Baousse-Rousse cave was named in his honour. Albert's intellectual achievements gained him worldwide recognition and in 1909, the British Academy of Science made him a member.

On 21 September 1869 at the Château de Marchais (which is still in the possession of the Grimaldi family today) in Champagne, Prince Albert was married to Lady Mary Victoria Hamilton (1850–1922), of Lanarkshire, Scotland, a daughter of the 11th Duke of Hamilton and his wife, Princess Marie Amelie of Baden. The couple met for the first time in August 1869 at a ball hosted by the Emperor and Empress of France; their marriage had been arranged by Albert's grandmother Caroline.

Caroline had tried to make a match between Albert and Princess Mary Adelaide of Cambridge, the first cousin of Queen Victoria, and sought the help of Napoléon III (Louis-Napoléon Bonaparte) and his wife, Empress Eugénie. The Emperor convinced Caroline that Queen Victoria would never allow a relative of hers to marry into a family who made a living out of gambling. He then suggested Mary, his third cousin once removed and sister of his good friend, the 12th Duke of Hamilton, as a suitable alternative. Mary was a granddaughter of Charles, Grand Duke of Baden and related by blood to the French Imperial family through her maternal grandmother Stéphanie de Beauharnais, Emperor Napoléon I's adopted daughter and second cousin of Napoléon III's mother, Hortense de Beauharnais. The Hamiltons were well aware of the extent of Monaco's estate, which was no bigger than theirs, but were sufficiently impressed by its status as an independent principality. The couple married at Château de Marchais on 21 September 1869.

Within a year of their marriage, the couple's only child (Louis) was born, but Mary disliked Monaco and found the Mediterranean too hot. While Albert was away fighting in the Franco-Prussian war, she left Monaco permanently. The couple divorced and their marriage was annulled by the Church on 3 January 1880, although a special provision was made by the Vatican to allow Louis to remain legitimate in the eyes of the Church. Civilly, the marriage was dissolved on 28 July 1880, by the Order of Prince Charles III. That same year, the former Princess of Monaco remarried in Florence, Italy, to a Hungarian nobleman, Prince Tassilo Festetics von Tolna.

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.

Despite the initial success of the marriage of Prince Albert and Princess Alice, in 1902, they separated legally, without issue, though did not divorce. According to Anne Edwards' book The Grimaldis of Monaco, this was due to the Princess's friendship with the composer Isidore de Lara. By the same token, the courtesan Caroline Otero, La Belle Otero, who had served him as a high class prostitute between 1893 and 1897, recalled Albert fondly in her memoirs and claimed that he was not a virile man and suffered from erection difficulty. Princess Alice had La Belle Otero banned from the principality in 1897 for being seen with her husband.
