Question: What is the date of death of Victoria, Princess Royal's father?

Knowledge 1: Victoria, Princess Royal
Victoria, Princess Royal(Victoria Adelaide Mary Louisa; 21 November 1840 – 5 August 1901) was German Empress and Queen of Prussia by marriage to German Emperor Frederick III.She was the eldest child of Queen Victoria of the United Kingdom and Prince Albert of Saxe-Coburg and Gotha, and was created Princess Royal in 1841.She was the mother of Wilhelm II, German Emperor.Educated by her father in a politically liberal environment, Victoria was betrothed at the age of sixteen to Prince Frederick of Prussia and supported him in his views that Prussia and the later German Empire should become a constitutional monarchy on the British model.Criticised for this attitude and for her English origins, Victoria suffered ostracism by the Hohenzollerns and the Berlin court.This isolation increased after the rise to power of Otto von Bismarck (one of her most staunch political opponents) in 1862.Victoria was empress for only a few months, during which she had opportunity to influence the policy of the German Empire.Frederick III died in 1888 – just 99 days after his accession – from laryngeal cancer and was succeeded by their son William II, who had much more conservative views than his parents.After her husband's death, she became widely known as Empress Frederick (German: "Kaiserin Friedrich").The empress dowager then settled in Kronberg im Taunus, where she built Friedrichshof, a castle, named in honour of her late husband.Increasingly isolated after the weddings of her younger daughters, Victoria died of breast cancer on 5 August 1901, not long after her mother's death on 22 January 1901.The correspondence between Victoria and her parents has been preserved almost completely: 3,777 letters from Queen Victoria to her eldest daughter, and about 4,000 letters from the empress to her mother are preserved and catalogued.These give a detailed insight into the life of the Prussian court between 1858 and 1900. [SEP] Knowledge 2: Albert, Prince Consort
Prince Albert of Saxe-Coburg and Gotha(Francis Albert Augustus Charles Emmanuel; 26 August 1819 – 14 December 1861) was the husband of Queen Victoria of the United Kingdom of Great Britain and Ireland.Born in the Saxon duchy of Saxe-Coburg-Saalfeld to a family connected to many of Europe's ruling monarchs, at the age of 20 Albert married his cousin, Victoria; they had nine children.Initially he felt constrained by his role of prince consort, which did not afford him power or responsibilities.He gradually developed a reputation for supporting public causes, such as educational reform and the abolition of slavery worldwide, and was entrusted with running the Queen's household, office and estates.He was heavily involved with the organisation of the Great Exhibition of 1851, which was a resounding success.Victoria came to depend more and more on Albert's support and guidance.He aided the development of Britain's constitutional monarchy by persuading his wife to be less partisan in her dealings with Parliament—although he actively disagreed with the interventionist foreign policy pursued during Lord Palmerston's tenure as Foreign Secretary.Albert died following a long illness at the relatively young age of 42.Victoria was so devastated at the loss of her husband that she entered into a deep state of mourning and wore black for the rest of her life.On her death in 1901, their eldest son succeeded as Edward VII, the first British monarch of the House of Saxe-Coburg and Gotha, named after the ducal house to which Albert belonged.
