Charles Beaubrun was born at Amboise, a member of a distinguished family of painters.
He and his cousin Henri Beaubrun (II) (1603–1677), were portrait painters in the courts of King Louis XIII and Louis XIV of France.
[1] His youngest brother, Michel Beaubrun (d 1642), was also a painter.
Beaubrun made many portraits of the reigning French queens, painting according to the prevailing court conventions.
Thus certain similarities are evident between his portrait of Maria Theresa of Spain (Maria Theresa, Infanta of Spain), queen to Louis XIV, and an earlier portrait of Anne of Austria, queen to his father Louis XIII (both shown here) even wearing the same regal gowns.
