Albéric Magnard (1865 - 1914) was a French late romantic composer, and one of the first cultural casualties of the Great War: he refused to surrender his property to German invaders and died defending it (Wikipedia).
His style of composition was somewhere between César Franck and Anton Bruckner, and I enjoyed everything I heard of him. His oeuvre includes four substantial symphonies, chamber music, and an opera, Guercoeur, that's well worth hearing. He may not be of the same level as his more famous contemporary countrymen Debussy, Ravel and Fauré, but he's worth exploring.
Some recommended works: symphonies 3 and 4, the string quartet, and the aforementioned opera. A good starting CD would be the combination of his two last symphonies on a Naxos disc (Amazon link).
