Louis Dorus was a 19th-century French classical flautist. Vincent-Joseph van Steenkiste, his real name, was instrumental in the adoption of the modern concert flute. He is the younger brother of Julie Dorus-Gras, the father of the singer and pianist Juliette Vansteenkiste called Dorus, known after her marriage as Rabaud-Dorus, and Henri Rabaud's grandfather.
