In 1863, he began his art studies at the École des Beaux-Arts, Paris.
During this period he learned etching techniques under masters such as Maxime Lalanne and Jules-Ferdinand Jacquemart [fr] (1837–1880).
Brunet-Debaines thus spent a considerable part of his prolific career in London and Scotland, and regularly exhibited at the Royal Academy between 1872 and 1886.
Museums in France and Britain include examples of his etchings in their permanent collections.
Many of his works appeared in The Art Journal, an important Victorian annual dedicated to the visual arts and publishing original etchings by artists such as Axel Haig, James McNeill Whistler, Seymour Haden, Hubert von Herkomer, John MacWhirter, Birket Foster and others.
