Frederick William George Adolphus, Landgrave of Hesse (German:Friedrich Wilhelm Georg Adolf von Hessen-Kassel; 26 November 1820 – 14 October 1884) was the only son ofWilhelm I, Landgrave of Hesse-Kassel-Rumpenheim andPrincess Louise Charlotte of Denmark.[1]
Prince Frederick William of Hesse-Kassel was born in Copenhagen on 26 November 1820.[2] He moved to Denmark with his family at the age of three, and grew up there. He attended the university in Bonn, and then began a military career. In 1843 he was third in line for the Danish throne after the King's son and brother, Prince Ferdinand.[3]His siblings includedLouise of Hesse-Kassel, future Queen of Denmark,Princess Marie Luise Charlotte of Hesse-Kassel and PrincessAuguste Sophie Friederike of Hesse-Kassel.


On 28 January 1844, Frederick married Grand DuchessAlexandra Nikolaevna of Russia atSt Petersburg. Frederick had come to St Petersburg as a prospective bridegroom for her sisterOlga, but fell in love with Alexandra instead on the first evening he spent with the family. Although Olga was the elder daughter and also found Frederick to be an engaging young man, she stepped aside in favour of her sister, and even chaperoned the couple when they wanted to spend time together. The emperor and empress then gave their permission for Alexandra and Frederick to be married.
Alexandra became acutely ill with tuberculosis shortly before her wedding, and this complicated the pregnancy which soon followed. She was never well enough to travel to Hesse and take up her new position with her husband. They stayed in St. Petersburg, where her health rapidly declined. She went into labor prematurely, three months before the child was due, and gave birth to a son, Wilhelm. The infant died shortly after he was born, and Alexandra died later the same day. Her parents were devastated and their grief would last until the end of their lives. She was buried at the Peter and Paul Fortress in St. Petersburg. The son was buried in Rumpenheim, now a borough ofOffenbach am Main, Germany.[4]
In 1849 Frederick William joinedHMSCleopatra to train as amidshipman. TheCleopatra was reassigned toSingapore to take the place ofHMSMaeander.[5] She arrived in Singapore from Devonport via Rio de Janeiro under Captain Massie on 14 September 1849 and left withHMSReynard forLabuan and China on 10 October. The Singapore paper mistakenly described the Prince as the son of theDanish king but the king had no sons, he was an heir to the throne.[6][7]

On 26 May 1853, Frederick married Alexandra's first cousin,Princess Anna of Prussia (1836–1918), atCharlottenburg Palace inBerlin. Although they had six children together, Frederick and Anna were never emotionally close, and it is speculated that one reason was because Fritz was unable to overcome his grief for his first wife. The couple first lived in Denmark inDehn Mansion, a mansion Prince Frederick had bought in 1844.
His first wife wasGrand Duchess Alexandra Nikolaevna of Russia (1825–1844), daughter of EmperorNicholas I of Russia andCharlotte of Prussia.[1] Alexandra died in childbirth, delivering a son who was born three months prematurely, and who died on the day of his birth:
His second wife wasPrincess Anna of Prussia (1836–1918), the youngest daughter ofPrince Charles of Prussia andPrincess Marie of Saxe-Weimar-Eisenach.[1] They had six children:
He is important dynastically as a candidate for both the headship of the Hesse-Kassel dynasty (through his father) and for the Danish throne (through his mother). WhenFrederick William, deposed Elector of Hesse died in 1875, his sons were excluded from succession, because of hismorganatic marriage. Therefore, Prince Frederick William succeeded the latter as titular Elector of Hesse.
Frederick William died on 14 October 1884 at Hamburg.[1]
