He is widely considered one of the most important and influential composers of the 20th century. Ruth Stuber Jeanne ("née " Stuber; b. 13 May 1910, Chicago; d. 6 Apr. 2004, Newark, Ohio) was an American marimbist, percussionist, violinist, and arranger.  On April 29, 1940, she and Orchestrette Classique, an all female orchestra, premiered the "Concertino for Marimba and Orchestra" by American composer Paul Creston.  The performance was at Carnegie Hall.  Creston wrote Concertino for Stuber and dedicated it to the orchestra's director, Frédérique Petrides (pronounced "pe TREE dis"), who asked Creston to compose it.  Creston was in the Audience.  The 1940 program notes stated that "Concertino" was "the only work ever written for this instrument in serious form."  Jeanne was a tympanist with Orchestrette Classique. Georges Caussade (20 November 1873 – 5 August 1936) was a French composer, music theorist, and music educator.

He began teaching fugue at the school as well in 1921; a position his wife, composer Simone Plé-Caussade, took over in 1928.  Among his notable students are Jehan Alain, Georges Auric, Elsa Barraine, Lili Boulanger, Jean-Yves Daniel-Lesur, Georges Dandelot, Claude Delvincourt, Georges Hugon, Jeanne Leleu, Eugène Lapierre, Gaston Litaize, Paul Pierné, Georges-Émile Tanguay, Henri Tomasi, Marcel Tournier, and Marios Varvoglis.

Despite being considered “one of the outstanding French composers of the mid-20th century,” Barraine’s music is seldom performed today.  She won the Prix de Rome in 1929 for "La vierge guerrière", a sacred trilogy named for Joan of Arc, and was the fourth woman ever to receive that prestigious award (after Lili Boulanger in 1913, Marguerite Canal in 1920, and Jeanne Leleu in 1923).

The Canadian publishing company La Bonne Chanson has printed a number of his folksong arrangements.  His other unpublished works include several motets, the cantata "À la gloire de Jeanne Mance" (1942), and incidental music for "Antigone" and the biblical dramas "Jonathas" and "Tobie".
