Pierre Carrier-Belleuse

Later he studied with Alexandre Cabanel and Pierre Victor Galland at the École des Beaux-Arts.

Between 1914 and 1916, he and Auguste François-Marie Gorguet [fr] proposed, planned and supervised the creation of the Panthéon de la Guerre, which was the world's largest painting (45 ft. high and 402 ft. in circumference)[3] containing almost 5,000 portraits of notable French and Allied wartime figures, mostly sketched from life.

Twenty artists played a major role in its production, although many more made contributions.

It was exhibited in a specially constructed display building (which was demolished in 1960) next to the Hôtel des Invalides.

Later, it made its way to the United States, and reconfigured portions of it may now be seen in the National World War I Museum at the Liberty Memorial in Kansas City.
