Robert Cocks & Co. was a London-based music publisher founded in 1823 by Robert Cocks (12 October 1797, in Norfolk, England – 7 April 1887, in London).
The catalog of publications, before Robert Cocks died, is said to have exceeded sixteen thousand, and included many important treatises.
[1] When Cocks died, he was believed to be the oldest music publisher in the world.
[2] The firm introduced in London pianists Carl Czerny, Julius Schulhoff, and Alexander Dreyschock and published Rimbault and Hopins' history of the organ and also published pedagogical repertoire for the so-call "Schools" of Spohr, Czerny, Marx, Albrechtsberger, Reicha, and Cherubini.
Eventually the company became a division of Stainer & Bell.
