The Singer-Polignac Foundation (link in french) was created in 1928 by Winnaretta Singer, (link in french) Princess of Polignac (1865 -1943). It devotes itself to sponsorship activities in favor of the arts, letters and the human and medical sciences. It also organizes musical evenings. A short-lived group of 16 singers from Mélo'Men, called Ensemble vocal Borromée, took part in one of these evenings.
