Robert Edler (* November 10, 1912 in Heilbronn; † August 14, 1986 ibid.) was a German composer of choral music who appeared both under his own name and under the pseudonym Max Orrel.
n Edler's numerous compositions he drew inspiration from jazz, electronic music, and the serial series principle. While he tended to publish more complex compositions under his own name, he chose the pseudonym Max Orrel for more popular works.[3] Works by Edler have found their way into many choral songbooks. His estate, comprising twelve folders, is kept in the Heilbronn City Archives.
