Dennis Andrew Nilsen (23 November 1945 – 12 May 2018) was a Scottish serial killer and necrophile who murdered at least twelve young men and boys between 1978 and 1983. Convicted at the Old Bailey of six counts of murder and two of attempted murder, Nilsen was sentenced to life imprisonment on 4 November 1983, with a recommendation that he serve a minimum of 25 years; this recommendation was later changed to a whole life tariff in December 1994. In his later years, Nilsen was imprisoned at HM Prison Full Sutton in the East Riding of Yorkshire.
All of Nilsen's murders were committed at the two North London addresses where he lived between 1978 and 1983. His victims would be lured to these addresses through deception and killed by strangulation, sometimes accompanied by drowning. Following each murder, Nilsen would perform a ritual in which he bathed and dressed the victim's body, which he retained for extended periods of time, before dissecting and disposing of the remains by burning them in a bonfire or flushing them down a toilet.
Nilsen became known as the Muswell Hill Murderer, as he committed his later murders in the Muswell Hill district of North London. He died at York Hospital on 12 May 2018 of a pulmonary embolism and a retroperitoneal haemorrhage, which occurred following surgery to repair an abdominal aortic aneurysm.

Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was the monarch of Prussia from 1740 until 1786. He was the last Hohenzollern monarch titled King in Prussia, declaring himself King of Prussia after annexing Royal Prussia from the Polish–Lithuanian Commonwealth in 1772. His most significant accomplishments include his military successes in the Silesian wars, his reorganisation of the Prussian Army, the First Partition of Poland, and his patronage of the arts and the Enlightenment. Prussia greatly increased its territories and became a major military power in Europe under his rule. He became known as Frederick the Great (German: Friedrich der Große) and was nicknamed "Old Fritz" (German: der Alte Fritz).
In his youth, Frederick was more interested in music and philosophy than in the art of war, which led to clashes with his authoritarian father, Frederick William I of Prussia. However, upon ascending to the Prussian throne, he attacked and annexed the rich Austrian province of Silesia in 1742, winning military acclaim for himself and Prussia. He became an influential military theorist, whose analyses emerged from his extensive personal battlefield experience and covered issues of strategy, tactics, mobility and logistics.
Frederick was a supporter of enlightened absolutism, stating that the ruler should be the first servant of the state. He modernised the Prussian bureaucracy and civil service, and pursued religious policies throughout his realm that ranged from tolerance to segregation. He reformed the judicial system and made it possible for men of lower status to become judges and senior bureaucrats. Frederick also encouraged immigrants of various nationalities and faiths to come to Prussia, although he enacted oppressive measures against Catholics in Silesia and Polish Prussia. He supported the arts and philosophers he favoured, and allowed freedom of the press and literature. Frederick was almost certainly homosexual, and his sexuality has been the subject of much study. Because he died childless, he was succeeded by his nephew, Frederick William II. He is buried at his favourite residence, Sanssouci in Potsdam.
Nearly all 19th-century German historians made Frederick into a romantic model of a glorified warrior, praising his leadership, administrative efficiency, devotion to duty and success in building Prussia into a great power in Europe. Frederick remained an admired historical figure through Germany's defeat in World War I, and the Nazis glorified him as a great German leader prefiguring Adolf Hitler, who personally idolised him. His reputation became less favourable in Germany after World War II, partly due to his status as a Nazi symbol. Historians in the 21st century tend to view Frederick as an outstanding military leader and capable monarch, whose commitment to enlightenment culture and administrative reform built the foundation that allowed the Kingdom of Prussia to contest the Austrian Habsburgs for leadership among the German states.

Swami Vivekananda (; Bengali: [ʃami bibekanɔndo] ; IAST: Svāmī Vivekānanda ; 12 January 1863 – 4 July 1902), born Narendranath Datta (Bengali: [nɔrendronatʰ dɔto]), was an Indian Hindu monk, philosopher, author, religious teacher, and the chief disciple of the Indian mystic Ramakrishna. He was a key figure in the introduction of Vedanta and Yoga to the Western world, and the father of modern Indian nationalism who is credited with raising interfaith awareness and bringing Hinduism to the status of a major world religion.Born into an aristocratic Bengali Kayastha family in Calcutta, Vivekananda was inclined from a young age towards religion and spirituality. He later found his guru Ramakrishna and became a monk. After the death of Ramakrishna, Vivekananda extensively toured the Indian subcontinent acquiring first-hand knowledge of the living conditions of Indian people in then British India. Moved by their plight, he resolved to help his countrymen and found a way to travel to the United States, where he became a popular figure after the 1893 Parliament of Religions in Chicago at which he delivered his famous speech beginning with the words: "Sisters and brothers of America ..." while introducing Hinduism to Americans. He was so impactful at the Parliament that an American newspaper described him as "an orator by divine right and undoubtedly the greatest figure at the Parliament".After great success at the Parliament, in the subsequent years, Vivekananda delivered hundreds of lectures across the United States, England and Europe, disseminating the core tenets of Hindu philosophy, and founded the Vedanta Society of New York and the Vedanta Society of San Francisco (now Vedanta Society of Northern California), both of which became the foundations for Vedanta Societies in the West. In India, Vivekananda founded the Ramakrishna Math, which provides spiritual training for monastics and householder devotees, and the Ramakrishna Mission, which provides charity, social work and education.Vivekananda was one of the most influential philosophers and social reformers in his contemporary India, and the most successful missionaries of Vedanta to the Western world. He was also a major force in contemporary Hindu reform movements and contributed to the concept of nationalism in colonial India. He is now widely regarded as one of the most influential people of modern India and a patriotic saint. His birthday in India is celebrated as National Youth Day.
