Adolphe Sax
Antoine-Joseph Sax was born on 6 November 1814, in Dinant, in what is now Belgium, to Charles-Joseph Sax and his wife. While his given name was Antoine-Joseph, he was referred to as Adolphe from childhood. His father and mother were instrument designers themselves, who made several changes to the design of the French horn. Adolphe began to make his own instruments at an early age, entering two of his flutes and a clarinet into a competition at the age of 15. He subsequently studied performance on those two instruments as well as voice at the Royal Conservatory of Brussels.

Adelaide was born on 13 August 1792 at Meiningen, Thuringia, Germany, the eldest child of George I, Duke of Saxe-Meiningen; her mother was Luise Eleonore, daughter of Christian Albrecht, Prince of Hohenlohe-Langenburg. She was titled "Princess Adelaide of Saxe-Meiningen, Duchess in Saxony" with the style "Serene Highness" from her birth until the Congress of Vienna (1814–15), when the entire House of Wettin was raised to the style of "Highness". She was baptised at the castle chapel on 19 August. Her godparents numbered twenty-one, including her mother, the Holy Roman Empress, the Queen of Naples and Sicily, the Crown Princess of Saxony, the Duchess of Saxe-Gotha-Altenburg, the Duchess of Saxe-Coburg, the Duchess of Saxe-Weimar, the Prince of Hohenlohe-Langenburg, and the Landgrave of Hesse-Philippsthal-Barchfeld.
