Giulio Marco Bordogni (23 January 1789 – 31 July 1856), usually called just Marco Bordogni, was an Italian operatic tenor and singing teacher of great popularity and success, whose mature career was based in Paris.
Bordogni was born in Gazzaniga, near Bergamo, Italy. He was a product of the Bergamo tenor school which originated with Giacomo David and Gaetano Crivelli, and in which can be counted, in addition to David's two best pupils (namely his son Giovanni and Andrea Nozzari, both notable in Rossini's operas), and besides Bordogni himself, also Domenico Donzelli and Giovanni Battista Rubini .
Bordogni made his operatic debut in Novara in 1808 without initially meeting with much success. In 1813 he distinguished himself as a performer of the role of Argirio in Rossini's Tancredi at the Ferrara revival with a tragic ending and at the inauguration of the Teatro Re in Milan, and became later very active in promoting that composer's music. He appeared in many of Rossini's operas on their first presentation in various towns and theatres, mainly performing the roles originally sung by Giovanni David. In 1825 he created the role of Conte di Libenskof in Rossini's Il viaggio a Reims. He sang for many years at the Théâtre des Italiens in Paris. He became a in teacher at the Paris Conservatoire in 1823 and continued to teach there until shortly before his death, which occurred in Paris.
He was the author of a published singing method, and composed many sets of vocalises which remained in use for singers for a century afterwards. He was probably the most influential teacher of the English tenor Sims Reeves, who went to him in 1843: other students include Sophie Cruvelli and Giovanni Matteo Mario.
Bordogni was awarded the Légion d'Honneur on 10 May 1839 by M. de Gasparin, at the same time that it was awarded to the Director of the Opéra Duponchel, and to the composer Hector Berlioz, who wrote that Bordogni was the best singing-master of that period. His daughter Louise Bordogni sang successfully in New York City in 1834.
