December 15 Through History

Explanation: The return of Napoleon's remains from Saint Helena was a grand national ceremony orchestrated by King Louis-Philippe, nicknamed the "retour des cendres" (return of the ashes). The coffin was escorted by the Prince of Joinville, the king's son, aboard the frigate La Belle Poule. This ceremony aimed to reinforce the legitimacy of the July Monarchy by associating its image with imperial glory.

Explanation: Ludwig van Beethoven was baptized on December 17, 1770 in Bonn, which makes his exact date of birth slightly uncertain, although December 15 or 16 are the most likely dates. He composed nine symphonies, including the famous 9th with the final chorus "Ode to Joy", which became the anthem of the European Union, much of his work while he was deaf.

Explanation: The space rendezvous between Gemini 6 and Gemini 7 was a crucial milestone in the race to the Moon. The two capsules approached to within less than 1 metre of each other, though without docking. Mastering orbital rendezvous was essential for the future Apollo missions, which would require similar manoeuvres in lunar orbit.

Explanation: Gustave Eiffel designed the internal metal structure of the Statue of Liberty, gifted by France to the United States in 1886.

Explanation: The Zoé atomic pile (Zero energy, Uranium Oxide, Heavy water) was built at Fort de Châtillon, driven by Frédéric Joliot-Curie.

Explanation: The Francoist regime, established by Francisco Franco after the Spanish Civil War (1936-1939), gradually came to an end after the dictator's death in November 1975.

Explanation: The adoption of the maple leaf flag replaced the old Canadian flag, the Red Ensign, which featured the British Union Jack in its canton.

The new flag, with its red maple leaf on a white and red background, became official on February 15, 1965.

Explanation: Henri Becquerel discovered natural radioactivity in 1896, almost by accident, noticing that uranium salts exposed photographic plates without any exposure to light. He shared his Nobel Prize with Pierre and Marie Curie, who built on his work. The unit of measurement for radioactivity, the becquerel (Bq), was named in his honor.

Explanation: Zamenhof, a Polish ophthalmologist of Jewish origin, published in 1887 under the pseudonym "Doktoro Esperanto" (Doctor Hoping) the foundations of the language he had built.

Its regular and simple grammar aimed to promote international communication and peace between peoples.

Explanation: Trivial Pursuit was invented in Canada by Scott Abbott, a sports journalist, and Chris Haney, a photographer, in Montreal.
