Answer
Marshall Berman credited Baudelaire as the first Modernist. Berman believed that Baudelaire was the first to see and articulate the modern world as a world of contradictions, of fragmentation and alienation, of beauty and horror, of possibility and despair. Baudelaire's poetry, Berman argued, captured the essence of the modern experience, and his work paved the way for the development of Modernist art and literature.
