Along with his studies with Boulanger, Copland took classes in French language and history at the Sorbonne, attended plays, and frequented Shakespeare and Company, the English-language bookstore that was a gathering-place for expatriate American writers. Among this group in the heady cultural atmosphere of Paris in the 1920s were Paul Bowles, Ernest Hemingway, Sinclair Lewis, Gertrude Stein, and Ezra Pound, as well as artists like Pablo Picasso, Marc Chagall, and Amedeo Modigliani. Also influential on the new music were the French intellectuals Marcel Proust, Paul Valéry, Jean-Paul Sartre, and André Gide; the latter cited by Copland as being his personal favorite and most read. Travels to Italy, Austria, and Germany rounded out Copland's musical education. During his stay in Paris, Copland began writing musical critiques, the first on Gabriel Fauré, which helped spread his fame and stature in the music community.
