Joseph Jean-Baptiste Laurent Arban was born on February 28, 1825, in Lyon, France.

He was a French cornetist, conductor, composer, pedagogue and the first famed virtuoso of the cornet à piston or valved cornet. He studied trumpet with François Dauverné at the Paris Conservatoire from 1841 to 1845. After graduating from the Conservatory with honours, Arban began to master the cornet. He was appointed professor of saxhorn at the École Militaire in 1857 and professor of cornet at the Conservatoire in 1869. In 1864, he published his influential Grande méthode complète pour cornet à pistons et de saxhorn. In 1876, at the invitation of Alexander II, Arban conducted concerts in Pavlovsk. He apparently made a phonograph cylinder recording for the Edison Company shortly before his death. Arban's cornet method of 1864 is often referred to as the "Trumpeter's Bible" and is still studied by modern brass players. The Arban Method book is available by various publishers, with Carl Fischer and Alphonse Leduc being the most prominent.

He died on April 8, 1889, in Paris, France.

Thoinot Arbeau is the anagrammatic pen name of French cleric Jehan Tabourot, born on March 17, 1520, in Dijon, France.

He was a French theoretician and historian of the dance, whose Orchésographie (1588) contains carefully detailed, step-by-step descriptions of 16th-century and earlier dance forms. Ordained a priest in 1530, he became a canon at Langres (1547), where he was encouraged to pursue his studies by the Jesuits, who considered dance to be educationally important. Orchésographie is written in the form of a dialogue between the author and a student. Such dances as the pavane, gavotte, and allemande are not only exactly described but also usually illustrated and directly associated with their musical forms. The book also outlines principles that, more than a century later, formed the basis of the five fundamental positions of the feet in classical ballet. In addition to its wealth of technical information, it is an interesting account of social behaviour and manners.

He died on July 23, 1595, in Langres, France.

Frances Burney, also known as Fanny Burney and later Madame d'Arblay was born on June 13, 1752, in Lynn Regis, England, to the musician Dr. Charles Burney (1726–1814) and his first wife, Esther Sleepe Burney (1725–1762).

She was an English satirical novelist, diarist, and playwright. She began composing small letters and stories almost soon after learning the alphabet. She often joined her brothers and sisters in writing and acting in plays. She educated herself by reading from the family collection, including Plutarch's Lives, works by Shakespeare, histories, sermons, poetry, plays, novels, and courtesy books. A Burney family friend, the "cultivated littérateur" Samuel Crisp, encouraged Burney's writing by soliciting frequent journal letters from her that recounted to him the lives of her family members and social circle in London. The first entry in Frances Burney's journal was dated March 27, 1768, and addressed to "Nobody." The journal itself was to extend over 72 years. A talented storyteller with a strong sense of character, Burney kept the journal diary as a form of correspondence with family and friends, recounting her observations about life events. Burney's Evelina, or the History of a Young Lady's Entrance into the World, was published anonymously in 1778. The novel was a critical success (four immediate editions) and admired for its comic view of wealthy English society and realistic portrayal of working-class London dialects. In 1779, she published a satirical comedy, The Witlings, followed by Cecilia, or Memoirs of an Heiress, in 1782. In 1786, she accepted the post "Keeper of the Robes" offered by the Queen, with a salary of £200 per annum. After the French Revolution began in 1789, Burney was among many literary figures in England who sympathized with its early ideals of equality and social justice. She became close to General Alexandre d'Arblay (1748-1818), an artillery officer and a hero of the French Revolution. Despite Burney's father disapproving of d'Arblay's poverty, Catholicism, and ambiguous social status as an émigré, they married in 1793 and had a son, Alexander Charles Louis (1794-1837). She continued writing, e.g., Camilla, or a Picture of Youth (1796), Love and Fashion, A Busy Day, and The Woman Hater (1797-1801). In 1811, she underwent a mastectomy due to breast cancer. In 1814, she published the novel The Wanderer: Or, Female Difficulties, set in the French Revolution, criticizing the English treatment of foreigners in the war years. In homage to her father, she published three volumes of the Memoirs of Doctor Burney in 1832. In 2002, the Burney Society of North America and the Burney Society UK unveiled a memorial panel in the new Poets' Corner window in Westminster Abbey in memory of Frances Burney.

She died on January 6, 1840, in Bath, England.
