Johann Georg Albrechtsberger

1736 (Klosterneuburg, Austria) – 1809 (Vienna)

Albrechtsberger was among composers sought out by Kraus on a long visit to Vienna in 1783. Michael Haydn had been a fellow-student, and both Haydn brothers were friends of Albrechtsberger, as also was Mozart, of whom he was very fond. Hummel, Czerny, Moscheles, Weigl and Beethoven were among his pupils.

Jean-Philippe Rameau

1683 (Dijon, France) – 1764 (Paris)

Voltaire was both friend and collaborator, working with Rameau on a comedy ballet and several operas. Martini was a correspondent. Boucher, Crébillon and Piron were fellow-members of a singing club: Piron co-wrote a comic opera with him. Diderot and d’Alembert had been friends, but Rameau’s disputatiousness over the Encyclopédie’s treatment of French music made good relations difficult; He had a major spat with Rousseau, who had written the entry.
