Polgár was born in Boulogne-Billancourt, the son of André Polgár, an engineer, CEO and Catherine Gauthier, an artist painter. On 25 April 1970, he married Kinga Bonay. Together they have a child.
He was organist and Kapellmeister of the churches of Saint-Cloud from 1964 to 1980 and also conductor of the Choir and the Baroque Ensemble of Saint-Cloud from 1972 to 1984. He was co-founder in 1974 of the Gregorian Choir of Paris. A specialist of Gregorian chant, he made several discographic recordings there, two of which were recorded by Erato. After having taught harmony at the Sorbonne from 1971 to 1980, in 1980, he was appointed deputy choir director at the Paris Opera, a position he held until 1992. From 1992 to 2001, he was conductor of the choirs of Radio France, "the only large French professional choir with a symphonic vocation". At the head of this internationally renowned choir, he was able to work in collaboration with the most prestigious conductors, and perform most of the major choral works in the lyrical and symphonic repertoire from the 18th to the present day. From his training as an organist and musicologist, Polgár was confronted with the problems of interpretation of 17th century music, which he often conducted at the head of early music ensembles. A music educator, Polgár has been in charge of the musical training of the Paris seminarians since 1990 and the seminarians of Nanterre since 2006. A lecturer at the Cathedral School, he is also a consultant and broadcaster on the television channel KTO. Since 1983, Polgár conducts the choir in Sainte-Croix de Neuilly with which he regularly gives concerts, organises tours and records CDs. In 1997, with the choir of Radio France, he received a Victoire de la musique classique in the "Ensemble vocal" category for the recording of the Gloria by Francis Poulenc. During the visit of Pope Benedict XVI to Paris on 13 September 2008, Polgár was chosen as co-director of the choir of more than 2000 choristers gathered on the esplanade of the Invalides. In 2009–2010, Polgár was musical advisor and singing director, for the film Of Gods and Men by Xavier Beauvois about the Murder of the monks of Tibhirine. Since 2010, Polgár has been performing regularly with his boys' choir the Petits chanteurs de Sainte-Croix de Neuilly, with pieces such as the opera Dido and Aeneas by Purcell, the Requiem by Mozart and Fauré, and more recently in 2015, with cantatas BWV 4 and BWV 140 by Johann-Sebastian Bach, which he performed with the Orchestre de musique sacrée de Paris.
