from the chemist and entrepreneur Armand Séguin, for whom he gave private concerts and composed more than 100 quartets. He composed revolutionary and patriotic anthems for the newborn Republic. He taught violin, voice and composition privately. In addition, he transcribed opera arias of other authors for any buyer. He accepted editorial commissions (in 1795, the editor Gavreaux asked him to attend to the reprinting of methods for violin by Francesco Geminiani, and in 1799 Nademann and Lobry hired him to edit one for flute). Oblivion At the beginning of the 1800s, Cambini signed contracts with periodicals and magazines, including the Allgemeine musikalische Zeitung and Tablettes de Polymne, which published his articles until 1811. From that moment, Cambini disappears without leaving any trace in any documents. Michaud affirms that he died in Holland in 1818, information that satisfies scholars and has a certain amount of credibility, while Fétis recounts his painful and tragic admission to a mental hospital in Bicêtre, where he was found dead in 1825. Sources There proves to be more than 600 examples of works by Cambini diffused throughout the world. More than 300 consist of printed editions, 250 are in manuscript copies, and about 100 are proven autographs. We have received only his instrumental music. In fact, only the music of Le Tuteur avare, written in collaboration with Pasquale Anfossi in 1787 (today preserved at the Bibliothèque Municipale de Lille) remains of his operas. For many years, there was a symphony that was considered to be his, but in reality it is by Joseph Martin Kraus for Boyer publishers. From 1784 to 1786, the publisher released the work of the then unknown Kraus under the name of the more famous Cambini in order to sell more copies, causing the misunderstanding of attribution, which was not resolved until 1989. Autographs All 100 known autographs are in the United States of America, at the Library of Congress in Washington D.C. and at the New York Public Library for the Performing Arts. Manuscripts The largest collection of manuscripts of Cambini's compositions are found in Prague, in the music history department of the National Czech Museum of Music. Following, in order of the number of preserved copies are: the Benediktinerstift der Bibliothek und Musikarchiv die Seitenstetten in Austria (the majority however are without a date)), the Conservatorio Benedetto Marcello di Venezia (Torrefranca and Correr Collection), and the Biblioteca di Archeologia e
