Carl Hauptmann (1858 – 1921) was a German writer and brother of the more famous Gerhart Hauptmann. Like his brother, he wrote naturalistic dramas including Marianne (1894) and Ephraims Breite (1898), but then turned to symbolism. His best novel is Mathilde (1902), a novel exploring the soul of a young factory worker. IMDB
