Edition Wilhelm Hansen, formerly known simply as Hansen, is a Danish music publishing company based in Copenhagen. Currently owned by the Wise Music Group, it was for the majority of its history a family-owned and operated business. Begun by Jens Wilhelm Hansen in his home in 1853, the company was officially incorporated in 1857. The majority of the company was sold to Music Sales Corporation (now Wise Music Group) in 1988 at which point it was re-named Edition Wilhelm Hansen. The Hansen family still maintains close ties to the company with Loui Törnqvist, a descendent of Wilhelm Hansen, currently leading the company.
