1778 Died: Jean-Jacques Rousseau, Swiss philosopher and polymath (b. 1712)
Jean-Jacques Rousseau (28 June 1712 – 2 July 1778) was a Genevan philosopher, writer, and composer. His political philosophy influenced the progress of the Enlightenment throughout Europe, as well as aspects of the French Revolution and the development of modern political, economic, and educational thought.
His Discourse on Inequality and The Social Contract are cornerstones in modern political and social thought. Rousseau's sentimental novel Julie, or the New Heloise (1761) was important to the development of preromanticism and romanticism in fiction. His Emile, or On Education (1762) is an educational treatise on the place of the individual in society. Rousseau's autobiographical writings—the posthumously published Confessions (composed in 1769), which initiated the modern autobiography, and the unfinished Reveries of the Solitary Walker (composed 1776–1778)—exemplified the late-18th-century "Age of Sensibility", and featured an increased focus on subjectivity and introspection that later characterized modern writing.
Rousseau befriended fellow philosopher Denis Diderot in 1742, and would later write about Diderot's romantic troubles in his Confessions. During the period of the French Revolution, Rousseau was the most popular of the philosophers among members of the Jacobin Club. He was interred as a national hero in the Panthéon in Paris, in 1794, 16 years after his death.

Victor Emmanuel II (Italian: Vittorio Emanuele II; full name: Vittorio Emanuele Maria Alberto Eugenio Ferdinando Tommaso di Savoia; 14 March 1820 – 9 January 1878) was King of Sardinia from 1849 until 17 March 1861. At that point, he assumed the title of King of Italy and became the first king of a united Italy since the 6th century, a title he held until his death in 1878. The Italians gave him the epithet of Father of the Fatherland (Italian: Padre della Patria). The monument Altare della Patria (or Vittoriano) in Rome was built in his honor.
Guglielmo Marconi, 1st Marquis of Marconi (25 April 1874 – 20 July 1937) was an Italian inventor and electrical engineer, known for his pioneering work on long-distance radio transmission,[5] development of Marconi's law, and a radio telegraph system. He is credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".
Marconi was also an entrepreneur, businessman, and founder of The Wireless Telegraph & Signal Company in the United Kingdom in 1897 (which became the Marconi Company). He succeeded in making an engineering and commercial success of radio by innovating and building on the work of previous experimenters and physicists. In 1929, Marconi was ennobled as a Marchese (marquis) by King Victor Emmanuel III of Italy, and, in 1931, he set up the Vatican Radio for Pope Pius XI.

Olav V (born Prince Alexander of Denmark; 2 July 1903 – 17 January 1991) was King of Norway from 1957 until his death.
Olav was the only child of King Haakon VII of Norway and Maud of Wales. He became heir apparent to the Norwegian throne when his father was elected King of Norway in 1905. He was the first heir to the Norwegian throne to be brought up in Norway since Olav IV, and his parents made sure he was given as Norwegian an upbringing as possible. In preparation for his future role, he attended both civilian and military schools. In 1929, he married his first cousin Princess Märtha of Sweden. During World War II his leadership was much appreciated and he was appointed Norwegian Chief of Defence in 1944. At his death in 1991, he was the last surviving grandchild of Edward VII of the United Kingdom and Alexandra of Denmark.
Due to his considerate, down-to-earth style, King Olav was immensely popular, resulting in the nickname Folkekongen ("The People's King"). In a 2005 poll by the Norwegian Broadcasting Corporation, Olav was voted "Norwegian of the Century"
