Louis-Albert Bourgault-Ducoudray () was a French Breton composer, pianist, and professor of music history/theory at the Conservatoire de Paris as well as a Prix de Rome laureate. He was born at Nantes and died at Vernouillet, near Dreux. Debussy was one of his protégés. His bucolic upbringing near the family estate of Grézillières certainly added to his eventual fascination with the folklore, music, and culture of Brittany and other nations. Later in life, Bourgault would support the Breton Regionalist Union, a Celtic organization indebted to the propagation of Breton culture, ideals, and the notions of independence. He was also represented in the Goursez.
