Louis Guglielmi (3 April 1916 – 4 April 1991), known by his nom de plume Louiguy (French pronunciation: ​), was a Spanish-born French musician of Italian descent. He wrote the melody for Édith Piaf's lyrics of "La Vie en Rose" and the Latin jazz composition "Cerisier rose et pommier blanc", a popular song written in 1950, made famous in English as "Cherry Pink (and Apple Blossom White)", which was recast as a resounding mambo hit for Pérez Prado.
