context_page_description: The Laurent Halleux collection is the donation, to the library of the Royal Conservatory of Brussels, of printed scores and manuscripts from the Belgian violinist Laurent Halleux, by his daughter, Suzanne Keller-Halleux.
context_section_description: While it has been established that several manuscripts of the Halleux collection, autographs or copies, supported the worldwide or European creation of certain pieces such as the Quartet n°2 of Jerzy Fitelberg, the Quartet n°1 on Indian themes of Frederik Jacobi or 4 Indiscretions of Louis Gruenberg, the score of Quartet n°2 of Roy Harris, also globally premiered, represents a remarkable case: two handwritten versions of the same piece coexist, esp. of the third movement.
