Louis Marchand (2 February 1669 – 17 February 1732) was a French Baroque organist, harpsichordist, and composer. Born into an organist's family, Marchand was a child prodigy and quickly established himself as one of the best known French virtuosi of his time. He worked as organist of numerous churches and, for a few years, at the French court. Marchand had a violent temperament and an arrogant personality, and his life was filled with scandals, publicized and widely discussed both during his lifetime and after his death. Despite his fame, few of his works survive to this day, and those that do almost all date from his early years. Nevertheless, a few pieces of his, such as the organ Grand dialogue in C and Fond d'orgue in E minor, have been lauded as classic works of the French organ school.

The composer was born in Lyon. Évrard Titon du Tillet, writing in 1732, described Marchand's father as a "mediocre organist". The son, however, was a child prodigy. According to the same source, Louis became organist of the Nevers Cathedral when he was just 14 years old; Titon du Tillet also states that ten years later, at the age of 24, Marchand obtained a similar position at the Auxerre Cathedral, but contemporary sources seem to indicate that the biographer was wrong, and Marchand settled in Paris before he turned 20. He married a Parisian, Marie Angélique Denis, in 1689, and worked as organist in numerous churches until 1707–8, when he became one of the King's organists at the court. Between 1713 and 1717 Marchand went on a long concert tour of Germany; after he returned, he settled in Paris once again and worked as organist at Église des Cordeliers until his death, augmenting his income with teaching.

Joseph Payne (2 March 1808, Bury St Edmunds – 30 April 1876, Bayswater) was an English educationalist and the first Professor of Education at the College of Preceptors in London.

He was born in Bury St Edmunds in Suffolk. He to came prominence as one of the most vocal adherents of the methods of Joseph Jacotot in England, publishing in 1830 an exposition of Jacotot's methods and lecturing to other teachers about education while teaching at a school in the New Kent Road, London. In 1838 he established Denmark Hill Grammar School with David Fletcher. In 1845 he opened the Mansion grammar school, at Leatherhead in Surrey. The school was very successful in exams and followed a detailed curriculum. Initially the pupils studied spelling and writing, history and geography, French, word and object lessons, arithmetic. As they progressed, English grammar, botany, and physics were added and at the age of 12, Latin German, mathematics, English literature, and physics were introduced. Chemistry would be added in the final two years.
