Russell's nationality was American, but, at the same time, he never denied his Mexican ethnicity. The name change was simply a means to an end. The explanation could be as simple as Arnheim did not like the sound, wanted something easier to pronounce, and chose "Russell" because it reminded him of Russ Columbo (a vocalist and violin player associated with Arnheim and his Orchestra who had already gained popularity before his untimely death). "Russ Columbo" was a stage name, as his birth name was "Ruggiero Eugenio di Rodolpho Colombo".
